Rebirth | '58 Fender 5F6A Bassman Pt 4

[@dennisflock3958]

The doghouse solution is cooler than the other side of the pillow.

[@MarcCarriage121]

The dog house looks awesome, more room , less weight. Upgraded parts. Can't complain about that. I wouldn't care what you put in the amp if it was mine as long as it was functioning properly and done with skill. That's all I would ask . To hell with the price ,but I noticed you do a great job at giving good service to the amps and at the same time try to help the owner to save $$. Your a 1 in a million service. Dependable, trustworthy, and skilled. 👍😎

[@CaptainRon1913]

Couldn't have said it better myself

[@Paul-mn8ql]

I don‘t know a darn thing about amps and all the tech but I know a quality repair job when I see one. Just wow!

[@Murry_in_Arizona]

Lyle, thank you, thank you, thank you! That's the slickest way I've seen to deal with the filter caps!

[@jamesmusicproducts]

...that doghouse solution is some damn fine work!

[@mistermac56]

Excellent solution to the doghouse caps. Wonderfully done with high quality and reliable Nichicon caps.

[@BradsGuitarGarage]

I'm convinced they only make Spragues that large to sell them to smuggling operations. So much air in them! Fantastic solution and explanation for the cap choices, mate!

[@johndelves9331]

I can honestly say I was seriously waiting in anticipation to see how you were going to do the filter caps in this setup! I'm OK now. I really like how it is like 'know one will know its not original' but in a good way. We'll have to do stuff like this more as these amps and type of circuits are to stay alive and working for a living. Love it.

[@mattjohnson6916]

Lyle, that is an absolute work of art! Those Nichicon caps look great and this owner will be VERY happy with the end result. I cannot thank you enough for turning me on to those caps. I've used them in all my builds now for over a year and they have been great. Thanks also for answering all my questions in the live chats on Vox circuits. My AC15 build is coming along fine, and I understand the circuit MUCH more than when I first started brainstorming on it. It's been interesting stepping out of my usual comfort zone of 60s Fender circuits.

[@rob-french-data]

This doghouse solution is just great! Love it, despite the fact that it is now a computer 😂

[@martinreid1740]

That's a great solution for the doghouse. When you're finished that amp will be better than new. Thanks for posting.

[@joemcgraw5529]

Very Beautiful and quality work Lyle and better than stock from 66 years ago

[@rickbaker4571]

Snoopy is safe... that is a bullet-proof doghouse!

[@EddieLeeFunn]

Nothing quite like hearing Lyle's YT troll voice early in the day! 😆

[@weschilton]

Very elegant solution for the filtering, and as always very clean work. :)

[@ryanguitargreene830]

I truly believe you are the best amp tech on KZbin I wish I could have my deluxe reverb serviced by you or at least ask a few questions. Thanks for your knowledge and videos

[@vadenk4433]

That looks great Lyle! That's a much better solution than using axial caps that would've been pushing themselves to their limit every single time you turned the amplifier on. That Bassman is way too valuable to use anything other than the best available solution. Bravo good sir!

[@bertrodriguez3087]

Nichicon's are awesome capacitors. Great idea.

[@colbyjack7074]

This is amazing. Super well done.... and beautiful. Plus the video and voice over a super well done.

[@Splattle101]

Very nice work, as usual. Elegant solution to the filtering problem, too.

[@IainThacker]

That's a really elegant solution to the unavailability of quality single caps of the ideal values! Loving the attention on th re-done wiring too.

[@wesleymorris1]

I use the same caps in all my repairs and my builds, nichicon are great caps, never had a failure .

[@stevencraig]

I like the troll voicing. It helps keep the comments clean.

[@macintune]

This is impressive engineering and beautiful execution! Look forward to hearing it.

[@kmetal83]

You are the best repair tech EVER

[@sgt.grinch3299]

I am always learning. What a great solution for the doghouse.

[@HalHawkins-j8i]

Beautiful

[@cee128d]

Good call on the use of those Nichicon caps.

[@johnwilliamson467]

Very nice fix for the doghouse problem . Trolls need to stay under the bridge and out of the way of those who do .

[@chokkan7]

I've come to really appreciate the smaller radial caps such as you've used here; my crusty old brain still has trouble with the better performance in a smaller package, but they do work well.

[@roberthastings708]

I so want you to do Bassman for me. You continue to impress. Thank you.

[@lonniezamarripa959]

Ah! It’s a thing Of beauty!

[@SirLoinMagroin]

Amazing work. The stories that amp could tell if only it could talk.

[@burnsy55]

Absolutely beautiful. I'd convert all my amps to modern radials if there were simple solutions to it.

[@Joshua_Stephens]

The Dog House cap array is clever.

[@nightraidone9768]

Really like your videos, even if i have nothing to with Amps anywhere else

[@fiddlix]

Great solution for a common problem in those amps. In Athens GA where I live wall voltages are frequently 126-128vac. It can be a real nightmare biasing current production el84 based amps.

[@merrillaldridge2775]

Elegant work. A couple of industrial electricians look over my shoulder during lunch watching these videos and have nothing but praise for the attention to detail. ?? Lyle, did you receive my e-mail regarding the 66 AC30 and 66 Bassman?

[@jerryking2418]

I like your filter cap solution. Yes, Sprague Atoms are terribly expensive and I agree their quality has sagged since the 1990s.

[@ditchgator1]

Beautiful 😎👍👍

[@thatampguy]

Solid Lyle

[@jasonkirkham550]

Your work is so neat ! It's no wonder people contact you to fix their amps.

[@DanielBobke]

1958 is not always > 2024. Just because it is "stock" does not mean it is better than what we can do with good parts today. Amps are meant to be played...not looked at in a time machine. Great job, Lyle.

[@butchlauer]

Bravo !

[@jcwear89]

It does look a bit like a computer though 🖥️ 😂 but I think its still looks really smart in the doghouse 👍🏻

[@paulwatson8809]

As a married man I concur that more room in the doghouse is a good thing.

[@victorbeebe8372]

Mahalo Lyle!

[@tedmich]

Doghouse is very nice! I might want some physical support in addition to the solder and silicone you've used to hold the caps up off the chassis, a EPDM foam strip could do this well (McMC)

[@PsionicAudio]

It’s planned.

[@TheModmc]

❤

[@chrisfit]

Soldering terminal strips would be a cool solution for a Princeton or champ.

[@Satchmoeddie]

Kudos on the bias trim pot!!! Trying to figure out the voltage drop on selenium rectifier stacks is a very inexact science, at best. The "around 1 volt per plate", is just pure nonsense, especially with half wave rectifiers. My 0-600 volt & new 0-1000 volt power supply projects have transformers that put out well over 2000 volts. Same deal, put 3 or 4 or 5 caps in series, shunted with balancing resistors, or "voltage dividers", as they are referred to on the schematics. One has 3 80 uF caps with 5K 50 watt resistors across each cap and the 1000 volt PSU has 4 100uF caps in series, with four 5K 100 watt resistor shunts.

[@NinerFourWhiskey]

Yeah, that's why I constructed a voltage bucker and always run my 1960 5F6A on it.

[@kurtwestphal]

how in the world do you get this so clean, and still protect the components?

[@MrStevehunter33]

Caps Off To Caldwell

[@matthewf1979]

I wish Nichicon made higher voltage axial electrolytic caps. What you did in the dog house is genius. Now, how to make a better ground than just 4 screws and metal to metal contact…..

[@PsionicAudio]

Thanks Matt. I’m not using the doghouse cover for ground. Just to solder the terminal strips to. And the caps have some non-reactive silicone beneath them. Ground wires are being run into the chassis ala AB763.

[@matthewf1979]

@@PsionicAudio I figured that’s what you’re doing.

[@johnbravo7542]

That power supply cap configuration looks great,I will borrow that technique for my next audio tube amp build. What was the value of the balancing resistors on the caps please?

[@PsionicAudio]

Thanks John. 220K ala Super Reverb.

[@johnbravo7542]

@@PsionicAudio thank you Lyle

[@classicraceruk1337]

Lyle I know nothing about electronics. In the U.K. we have 240 volts from the wall. How does this affect all the parts in an amp?

[@PsionicAudio]

Same as using a 120VAC primary transformer here. In theory the secondary voltages will be the same. But you can have this same issue. Is your “240” really that, or 230, or 255? The secondary voltages are a percentage of the primary voltage. As it changes, they change.

[@classicraceruk1337]

@@PsionicAudio Lol I have no idea how it varies!!!!!!!!!!! I just plug stuff in……….. I know the fuses my appliances need, that’s about it.

[@Strumbum01]

Mornin Lyle. Any advice on carbon comp vs carbon film resistors? I’d like to use 1/2 watt cc on a PR clone build but I’ve heard they’re noisy and prone to early failure. Thanks in advance!

[@PsionicAudio]

I use CCs in restorations but would use CFs for a new build.

[@Strumbum01]

@@PsionicAudio that makes perfect sense to me, Lyle. Plus those CC’s are a bit pricey. But I do like their vintage look. I appreciate the response. You’ve been very gracious, and helpful, in answering some of my questions over the years. I’d like to contribute to your tip jar but can’t find a link anywhere.

[@PsionicAudio]

Thanks Strumbum. If you insist, it’s a button on every video labeled Thanks.
