Which Capacitor Sounds Best? Tube Amp Capacitors #1

[@ryanacree]

I prefer the Mallory's as they bring forth more tone. The others just sounded more choked off. You can always roll off the treble, but you can't get it back, and when it sounds so muted like that, wow. I don't know what the difference in specs the Jupiter Yellow to the Red is, but the Red was certainly the worst. I would rank them like this: A, B, D, C. Thanks for setting this up!

[@jasonsheppard7428]

Mama is right. It was so close though. definitely won't be wasting money on expensive capacitors. Longevity and reliability seem to the the only worthwhile factors. Thanks for doing this experiment!

[@ChipsTipsforLife]

I would love to have the reveal at the end be that there were only Vishay ceramics in the box and the switches did nothing.

[@giulioluzzardi7632]

I agree with Mother, if it hurts your ears scrap it. Use the ones that make the listener and player happy. More tests please!

[@T3NN3SS3E]

Dude! I'm getting into building tube amps and have come to the part of the process where it's time to start ordering components. Good info here and even cooler than you're just up the road from me. 🤘

[@neilsnow7973]

To get a real value of how different they sound you need to have the amp at or past the point of breakup. Even fully distorted. That's usually when the "bees" come out in an amp. Having the amp in overdrive emphasizes the differences in the tone values by a lot more then a clean amp! Great test to do on your amp. I know a lot of people complain about amps having a fizzy tone when cranked up and changing caps can help sometimes.

[@robertfox499]

Pretty darn interesting comparison. I'm a ham radio operator who happens to love using the old AM mode of radio transmission as opposed to modern Single Sideband (SSB). With AM (amplitude Modulation)... sound differentiation is a big thing among us old hams. It is possible that the longer a charge remains on these capacitors (which are electro static in nature) the more similar they sounded and that relates to slightly different charging time constants. But I'm just guessin here. These are all pretty good caps you used. Thanks for the effort that went into this Prof. Dan. It was informative and illuminating. As a side note: If my dear mother in law were still alive - she wold be my number 1 "go to" for advise as well. It's nice to see a man who reveres his mom-in-law's opinion on things.

[@anthonybiegun8839]

these caps would have to be metered for exact value, I agree with the comment 10 percent plus /minus will vary the frequency response

[@fantsika]

B is the best to me , after C but more bright , thanks

[@thesjkexperience]

Ive always felt Orange Drops have a hard unmusical top end in tweed amps. I like the Mallorys as they are inexpensive and sound pretty good. Love to hear a paper in oil.

[@arsenicjones9125]

The only way to do this is with a loop so the performance is exactly the same and then do null tests where you invert the polarity of one of the recordings the play them back together to hear ONLY the differences. The plain fact is there is only minimal differences and you’re experiencing the placebo effect. bc you expect a difference you hear a difference. Now go change your speakers if you want your amp to sound different.

[@chippsterstephens6800]

It is clear, even on KZbin, A is harsh….you can’t hear that dude? Just wow.

I'm thinking there might have been ever-so-slight variations while the amp was warming, but as the experiment went on, it became difficult for me to notice any significant changes in the different caps. Very interesting video, Dan. Thanks for posting. Fred

[@RapperBC]

Interestingly, in a similar vein to your mother(-in law?)'s ears: my left ear had a muscle twitch which decreased on the chopped intro to "Jingle Bell Rock" on both C and D. It was repeatable. Really cool of you to set up this experiment, and a special thanks to ETSU and some East Tennesseeans, y'all- that's my neck of the woods! Grew up in J.C. and Kingsport.

Cool comparison rig! Would really like to see another comparison on an amp with some distortion in it. Nothing crazy, just like a cranked Deluxe Reverb. I think that's where the highs would make their presence(haha) known.

[@francisvancampenhout396]

do the the caps have the same value , these are 10% caps .In a tone stack this can vary the frequency response with plus and minus 10 %, thats what you hear 😊

[@rewind9536]

I listened to the samples with Sony WH1000XM4 headphones (€400 new) and I could not hear much of a difference in the high res files playing in VLC. But after a few more listenings, and cheating, I have formed an opinion: A Knowing from other peoples comparisons I now recognize the sharpness of the Orange drops in A. B is nice and clear, but is also quite sharp. C I didn't like C which sounded a little muffled. D sounds nice and mellow. A and B are very similar, C sucks, and D is just nice. But after learnimg more, I don’t want to damage my amplifier and drivers so I m going for regular poly caps.

[@Wim37u]

I thought the same as your mother in law and generally i dont care if it is from the caps or the speakers, i like some sparkle but dont want earbleed and that was difference in the caps but i just listened to it on my cell. Nice video.

[@Cpt_Adama]

Unless you checked the values of all the capacitors to verify that the values are all exactly the same your not accomplishing anything other than listening to what difference capacitance makes to the circuit. Those caps have a -/+ 20 % tolerance from the printed value. There should be less than 1% difference in value to make any kind of real differential between brands. I’m sorry but this test just doesn’t answer anything because your caps are not value matched.

[@DeadKoby]

[@firebald2915]

KZbin compression ruins it. The volume level you have mic'd isn't coming thru. They sound the same until the sound level tails off to a lower volume. ON the First strum test.

[@brianjuffs4662]

Did you measure the cap values? Tolerance is the major difference cap to cap.

[@Toobzilla]

i was wondering the same thing.

[@rickschiller]

A useful review as (1) the recording uses a properly placed SM57 Mic. and (2) listening to the downloaded mp3s with headphone allows a real comparison. Also thanks to ProfessorDan for making a realistic "apples to apples" comparison box with the 4 capacitor types. Clearly the Orange Drop 715/716 are the inferior cap here unless one wants a slightly thinner tone and a strident top end. While I think the Jupiter Round slightly came out on top, the Mallory 150 - at 1/7 the price - is very close and works. The Jupiter yellow being polyester film like the Mallroy150 is good but not quite there. How the capacitors will sound with more signal cranked into them would have been useful, to hear them with the amp well into clipping.

[@duanethompson2360]

I would have to change the capacitors in my phone to hear a difference !

[@pedrolourenco2707]

I would love to see some white noise applied and some frequency analysis of the sound without speaker. Maybe you could even do it without a tube amp...

[@josephlevine2836]

Did you measure capacitance and verify they were close in value? Caps have huge uncertainty. If you didn’t check, you are likely just listening to difference in capacitance. Which is interesting, but not repeatable or something someone can expect from buying a given brand. Thanks for the video tho, fun to watch :)

[@ArthurStone]

Yeah: B is tighter and darker treble; D has a punchy thump with brighter treble. Cool 'science experiment.' Valuable work. Thanks : D

[@faroutsessions3612]

[@giulioluzzardi7632]

Hello you Gents have done a great job. At this end the difference is more obvious when you play higher up the neck.Maybe do a similar test on one of the Fender Re-issue amps ? Listen to your Mother , she has super hearing! Thanks.

[@juanh9350]

Cool video, soon my tech will build a JCM 800 for me and I currently am searching for what components to use. I'd like to hear the same comparison with some distorted tones.

[@arsenicjones9125]

Have your tech buy whatever quality parts he needs cuz it makes no difference. The minor differences come from nebulous differences in the capacitors like their internal resistance and inductance. If they’d done a null test they’d have found the differences between caps to be so minimal as to be w/in the margins of error. So just buy quality caps from a reputable source and you’ll be fine. You do want to make sure your caps are oriented correctly also. Even non-polar caps have a preferred direction in tube circuits

[@arsenicjones9125]

[@thetriode]

What would be interesting is 1-Hook the capacitors to a bridge and see if tolerances come into play 2-Use a function generator with the capacitor and a resistor in series and see if the roll off varies on frequency.

Depends on the circuit but caps do make a difference, sometimes its very subtle but i have changed caps and distortion even measured different.

[@VintageDaedalus]

You will hear a difference if you build the entire amp with different capacitors and crank it up.... for sure. I build a Marshall with Jupiters and it was wrong in sound, way to 'cleanish'. Vishays MKT are my choice for Marshalls, they Sound brilliant and emphasize the roar the old ones did. Build an AB763 with Jupiters and it sounds fabulous. Cranked it up and was instantly in SRV's region with the help of a Strat. There this cleanish Sound works. Each brand will slightly emphasize or understate specific frequencies. Cranked this effect gets bigger. Not to mention power supply filter capacitors, which will also color the sound in a way. (Their value and even their brand, trust me) Ceramic vs. Silver Mica is also audible

Or better, take electronics class before making conclusions...😃

[@assymcgee1]

I believe there are subtle differences in the 4 capacitors. Albeit negligible. However, I believe that even 4 of the same value and brand of capacitor from different batches will each sound subtly different as well, perhaps even in a similar manner as this. As long as the physical construction and value is correct the brand (or color) is negligible.

[@rquance1]

Suggest using a noise source instead of the variable guitar player. The noise source is repeatable.

[@SinnerSince1962]

There is a huge problem with the analysis. Every amp reproducing this WAV file is going to treat the music differently. So, not only are we listening to a recording from YOUR amp, we are analyzing the results with OUR amp through OUR speakers. There are way too many variables in between to say one capacitor would be better than another. And... everyone's ears hear and interpret things differently. And each of our brains like different things. There is no right or wrong. I think the bottom line is buy the most reliable and cost-effective ones that suit your needs. The Mallory have a nice form factor that fits in a lot of tight places well. And, they do the job nicely.

[@qua7771]

The other Fender amp may have an entire chain of Orange Drops in its signal path. It would be interesting to hear the polyester 225P series Orange Drops.

[@cgavin1]

Those are the only orange drops people recommend too! Mallory 150's in mine and far more important in the AB763 signal chain are the low value ceramic coupling caps. The channel treble and especially the reverb mixer can be smooth as butter ice-pick city. The Phase Inverter coupling cap too. Probably the single most important cap in the entire circuit for filtering frequencies.

I think I preferred C or D, depending on the content. A was too snappy / bright and B was too scooped. That said, either of those could be used for voicing. Curious what the speaker was (sorry if I missed it) and why you didn't choose a more dynamic and cleaner sounding amp design as the test subject? A Twin Reverb with D130s would show it all.

[@timothymatthews4399]

Maybe this is asking too much, but if you have an oscilloscope or quality frequency analyzer, it would be more scientific also, as mentioned, you need to loop the exact same track again & again to be scientific. I could hear the difference on my iPhone 14 phone. Definitely, no question about it. Perhaps orange drop providing more top end “brilliance” is a good thing. I mean, guitars AND amps have tone knobs right?

Hello, i hear a quite bothering "clip" at each start of the picking short loop (8:18). This peaking clip is on B,C,D but not on A. My headphones (sony MDR7506) may be old or too bright, but the clip clearly dissapears on A so the difference should be valid and noticable (?) on any gear, cliping or not cliping. A bit shame that we don't hear the A position longer on this short loop session, only 1 bar at 8:18 then just 1 bar at the end. Then we are not shure if this clip really dissapears on A or if that is accidentaly due to position switching.. Thank's for sharing experience

[@noel3422]

Its not the sound of a capacitor but how each cap treats the small ac signal passed through it, but now days you can buy 20 different caps that have the same properties and different names, so caps no longer matter, you get a cap use a cap and hope for the best.

[@ehss192]

Maybe .2% of a difference to the overall tone. It may seem bigger in person but by the time it goes through a recording chain and comes out the other end of KZbin the difference is negligible. Put it in a mix with a live band and I doubt anyone could ever tell.

Some capacitors are rated with a 20% tolerance. if you test with a capacitor of -20% vs +20%, you will definitely here a difference. there should be no difference if both are exact same value.

[@cgavin1]

You are not wrong (as a rule) but don't discount the effect different dielectric material can have on two capacitors with the exact same value. ESR also plays a big factor.

[@killingmasheen]

​@@cgavin1 It's the mostly the difference in ESR we're hearing as well as it's self inductive properties. Large sized caps like Orange Drops are built up of multiple capacitive elements wired together in parallel cutting the total ESR and self induction. The way modern film cap manufacturers compensate for these losses is keeping the physical size of the cap as small as possible, a particularly important point in high frequency applications. To me, the most balanced sounding film caps are WIMAs. They have a good high end content without getting as harsh as Orange Drops in some designs. A good cheat if you want to mimic the high end response of an Orange Drop with a cheap film cap is bypassing it with a small value ceramic cap; ceramic caps have a near zero ESR. It's only a 2-3 picofarad difference but for guitar amp purposes you'd be hard pressed to hear any difference a between a 47p cap and 120p cap.

[@giulioluzzardi7632]

I found a happy compromise for a Stratocsster tone control; 1x .022uf mullard and a Wima .01 in parallel, the treble is clean and not harsh, rings and sustains and the bass end is tight and clear. I discovered a great tone by accident.

Pretty much the end of that argument if momma said….. Backs up what I have found over the years, like to have had some vintage blue molded caps into that mix, what values are you using? I could lend you some, if round two of this is being done, they are rare and expensive though , so would need them back, no esr or leakage at rated voltage have I ever found on a old blue molded cap, drift is very negligible, they are a special cap, imo, I have messed with clones for awhile now, like 40 plus years, and only blackface Circuits, I found the same a momma, orange drops are harsh, I stopped using them after a few amps, and used Mallory , that lead to using only vintage blue molded caps, after awhile, I build very small volume, that makes that possible, many hours with bode plots, study of wave forms in a daw, listening to what a sound engineer thought, had your mom been around it sure whole have saved me a ton of time…..lol Love the video man, thank you for posting it.

[@Jimel]

I was hearing much more difference during live play than the reamp, and not because different attack with the pick and variations of play, but as much as it seems the reamp was biased like not matching the same output resistor as the guitar pickups high output impedance. Or maybe the quality of converters during reccording, I don't know exactly but it seems to me a lot of details in the sound went out during reamping. Also not playing the same parts like chords versus solo must be in cause. Otherwise the Jupiter red is far superior than the others with much more details in the high end of the spectrum, better dynamics and sounds more open with air. the yellow Jupiter comes close behind but mallory and orange drop are not in the same competition. I'm listening through HD560S headphone L30 topping amp, fx audio pre-1 ge5654 tubes, d10S dac, realphones at around 115dB SPL peak. Before this setup I was on my pc headphone amp with the akg K702 and prefered the Jupiter yellow, because it was compensating for too much highs in my system. I mean one needs to have decent gear to hear subtleties which are not so subtle once at this level of definition. I react to comments stating all caps sound the same, this is very very wrong.

[@Turboy65]

If the VALUES are the same, the caps SOUND the same. You can prove this for yourself. Find caps that are different types but measure to exactly the same value and you'll never hear the difference. Find caps that are the same type but different values, and you WILL hear the difference.

Unfortunately, your test is flawed. May I make a few suggestions. I have done similar test here over the years and learned, people often have what they think is the best cap, tube, wire, audio tube, transistor/FET etc but here is a definitive test anyone can try. Firstly, chose a group of at least 4 to 5 people, around the same age in each group. Something someone in their 20's hears may be different than someone in their 50's and higher. 1) have a single source, CD, Tape, but not someone playing live 2) give your participants a sheet of paper and pencil 3) don't let the participants see what you are or are not selecting. 4) make the test simple, no more than 3 caps, tubes, wires etc at a time. 5) play your source through the various test items at least 5 time each. 6) have your participants write down what they THOUGHT they were listening to and ask for comments like, rich, dull, noisy, airy, etc. 7) compare your test results against what the participants claimed were better or worse. 9) repeat the same test with at least 3 groups of people. I have done this double blind test numerous times and with so called golden ear audiophiles with results all over the spectrum from each person. I once did this test with a $10k turntable and a $127 table. Both tables were using the same cartridge type, same, preamp amp, wires and speakers. Even repeating the test 3 times with 3 groups of people, the accuracy was ALWAYS below 30% got it right except for different types of "audio cables" vs lamp cord and the results were less than 20% got it right. Unfortunately, we are all guilty of being biased from what others tell us or what we read in magazines and online is even worse. I am guilty too of my own biases and would do as bad as those I have tested. The biggest area of snake oil and BS is in the area of audio. Does not matter if it's guitar amps, HI Fi systems etc. Having written this, I fully agree a sound system designed well with decent components will sound better than something which is of much lesser quality. Try this test and amuse yourself and your friends.

[@johannalvarsson9299]

As an audio-engineer I find it funny how both audiophiles and "anti-audiophiles" always talk about this stuff as if you couldn`t simply measure it. If you want to know if there is a difference, nulltest it. Simple as that. Yes, there is a lot of BS in the field of audio, but I think the food-industry is way worse. Also, there is also the other way around: the utmost majority of people cannot hear compression, even if you shove them 18dB of gain-reduction in their face. Because, as you said, the human hearing is way too subjective, and it`s not just personaly bias via knowledge, its also because your brain processes sound so hard that literally the colour of the wall you are looking at the time you listen to something will change your perception of what you hear. So while I agree that your methodical approach of testing is better than that of the video, it still gives no meaningful results. As said, that is what nulltests are for.

@@noel3422Well, I don't drink alcohol. I do have 50+ yrs working on electronics. To keep it short, it's the rating not the material that makes caps produce a diff. tone. I hear diff's of pico farads. that's way within the 5-10% tolerance for even good caps. .022 + 10% & .022 - 10%, will sound diff. No current EVER actually passes thru a cap, AC or DC. Electrons cannot pass thru the dielectric. If ANY current passed thru it's called a shorted cap. Caps charge and dis-charge. How fast determines freq. How much current is stored then released from and into the circuit to which they are connected.

No discernible difference. If you switched them blind I challenge anyone to hear the switching... With the caveat that this it KZbin. On the other hand most people who do music do it on KZbin these days, so...

[@asadabbasmirza9519]

Why r u conducting this test??? Rightly pointed out ,no values mentioned, .Better quality ones r within specied ratings..................in any case there is induced distortion in guitar amps . Even the play back amps don't have any difference unless v bad quality.....

[@peteleoni9665]

Other than the fact that there was virtually no difference, I am going to say that I, being a golden ear type of asshole could hear the difference. There is no difference. The amp sounds great, but the caps? Nope, you are fooling yourselves. I am in fact a mastering guy. There is nothing here that matters at all. We all better start being honest or people will start believing anything...... Oops too late...

[@johannalvarsson9299]

Just that the mastering guy knows how to technically measure a signal and find out if what they hear is imagination or real. It`s not called "engineer" for no reason. Audiophiles are very often completely mislead, but the anti-audiophiles are just as bad.

[@giulioluzzardi7632]

No-one really knows, we did'nt get to see inside the box. Maybe they were just switches wired in series and that may have been what we spent 10 mins listening to? We wanna know whats in the box next time.

[@timburle4980]

No difference on back to back plays.

[@AA_MusicGuy1111]

There's a difference. If you can't hear it then you just aren't an engineer and are a guitar player lol.

[@JayOneAlumni]

there's no difference at all

[@Leftlanedave]

I don’t hear a difference total snake oil
