Interesting ? Never used JJ tubes , I have a selection of vintage tubes that I swap but for new tubes EH is workable . In my Mc240 I can hear whatever changes tubes make. Telefunken is always nice.

Just recently got more serious about rolling quality, vintage preamp tubes in and out of my guitar amp and just want to say that I have been enjoying the content of your videos. Good stuff! 👍 So far, I'm really liking the Tungsram ECC83, after using a late 50's Baldwin-branded Raytheon Black Plate for the past few months. Both are VERY nice compared to the contemporary tube makes. Next up will be a GE-branded Mullard I63 Blackburn, like the tube you've shown here in this video.

うん0が出そう

thank you for your videos ...I have learned much from your vids.

Top ecc83

Is the jj sounds good in tube mic?

Correct me if I'm wrong, but the ECC83 has a more lush high end??

Very good explanation! TKS.

Are old chinese 12ax7’s better than modern jj’s?

Are they direct replacement ?

Perhaps also do a review of the Special Quality 6Н2П-EB(6N2P-EV) and 6Н2П-EB-OC(6N2P-EV-OC). The latter being the "space-grade" version Edit : I just also watched your 6N6P-EV comparison - Thank you for comparison !

hi. i tried the genalex b759 and it's good for a modern tube very balanced on my 1974x but nothing compares to vintage tubes.

Wow great demo. I like the better separation between instruments with the Voshods, they are a quieter but it doesn't matter really. Please could you tell me where you found your adaptators ?

6N2P by far, more dynamic

To understand the prices for radio tubes in Ukraine, you can buy 6n2p - 1 $ 6n2p -ev - 5$ ecc83 - 18-25$ Price-quality is in the lead 6n2p-ev.

6n2p are great tubes. I have lots of them and I have lots of valuable mullards etc. There are differences but not ones that reflect the price differences.. I build my guitar amps with a switchable circuit so that they can accommodate either. You'll want to ground pin 9 on the 6n2p. It's a sheild that runs between the triodes. And your heaters are pins 5 and 4. Otherwise they're wired like a ecc83

6n2p lamps have many disadvantages. This is a dispersion of characteristics, this is internal noise, this is self-excitation. I have a large number of them, I like to experiment. Want better quality? 6n2p-ev, 6n2p-v, 6n2p-i. Any of these lamps will be 50% better in all respects.

6Н2П has a very pronounced "airy" sound, very melodic and pleasant. ECC83 has a strong punch, the dynamics sound deeper with your amp. I would prefer the 6Н2П.

6Н2П for the win💡💥

Ei sound better to me, and didn’t noticed any microphonics

You forgot the PS Vane factory in China

I’ll stick with RCA black plates from the late 50’s - 60’s NOS with D shape getter with copper stress rods. Burned in for 24 hrs then thoroughly matched.

Great video. Thank you

This type of tubes can be used on a Fender Twin reverb? Great video. Many thanks

So why do the vintage sound better? Is it the material ? The way they were made? Why cant modern tube makes sounds as good as vintage ?

JJ's all the way

Really cool video. I liked the JJs more on the guitar-only tracks, but the New Sensor sounded much clearer in a mix to my ears. I'm currently deciding whether to splurge on some new preamp tubes for a Hiwatt and Marshall which have JJs and EH tubes, so this was really helpful. I know you mentioned your take in another video on the different New Sensor tubes, but I've been having a difficult time finding a direct comparison between the Sovtek LPS, the Mullard RI, and the Gold Lion gold pin (i.e., the 3 long-plate ECC83s from New Sensor). Could be a cool comparison!

Thanks for your videos, regards from England

I bought two boxes of these about 10 years ago, I think it was Bulgaria or somewhere, before the sanctions and they were not even a dollar a piece if I remember correctly. Built one Champ like amp with them and I prefer that amp to the 5F1 I also built.

Een Nederlander?

Why do the vintage tubes sound so much better than modern tubes.. I can hear clearly hear the difference in my AirPod pros it’s ridiculous the difference much less my studio monitors.. I’m replacing my tubes with nos tubes in my la 610 mk2 channel strip.. I can’t wait 😜.. how long do these tubes last ? I know it depends but in general sorry I’m new to hardware

Great video thanks from England

Would you mix a telefunken 12ax7 tube with other telefunken tubes in a stereo amplifier?

Another great video thank you from England

Great video thanks from England

50s have little more headroom, but 60s seem to have more interesting harmonics

I've found a Brimar e83cc. Do you know if it's any different then ecc83? Is it still good for a guitar amp?

Hello, how do I know which is the V1 position on an amp?

Tungsram is more much better!

I wonder if one could re-think the differences of tube tone, like if the JJs seem to have higher gain than the russian tubes in the lower registers - why not re-voice the circuit by changing the bias resistors and cathode bypass capacitors? Look at Marshall plexi circuits, you have the same v1 tube providing the first gain stage in both high treble and the normal channel - v1a vs v1b. But both are biased differently and have different cathode bypass capacitors - both channels have very different eq. Why not take an amplifier and re-voice it to give the same results with JJ tubes? Just start playing around with cathode bypass caps and coupling capacitors to neutralize the bass frequencies of JJs?

Philps is way wider and warm... Thank you for sharing...

NOS is a suckers market these days. Sure, they are superior, but if the set of tubes cost more than the equipment they are driving that's a big no-can-do from me.

For HiFi use, I think the 6N2P:s do not stand a chance to the 12ax7:s. Lack clarity and spatial qualities

Perché l adattatore per le 6n2p non entrano direttamente

I just bought a tube tester and put it to work. I tested three JJ tubes that had little use and all were bad, even a new EL34 that was a part of a matched quad - did not even register on the meter. A 6V6S from JJ that I bought for a guitar amp I built -bad. And an ECC81. I tested 2 Tung-Sol 12AX7 and they were brand new - both bad. I have a bunch of vintage tubes I tested from GE, RCA, Sylvania, Raytheon, Amperex and out of 50 tubes, 4 were bad. They just do not make tubes like they used to and one has to be careful.

I appreciate these kinds of videos. It really shows how little difference there is in recorded sound tubes make. Not saying that there's no difference. I prefer old US/Euro made tubes because they last for freaking ever.

I am fortunate I began collecting USA-made NOS tubes 30 years ago and I have some old RCA tubes that are still operating in my 1960s vintage tube amplifiers. I tried some newly manufactured tubes and they are OKAY if they come from highly tested tubes for noise etc. Most Chinese tubes have a short life and have very little sound character.

I obsessed with locating NOS decades ago and have several lifetime supplies of preamp and power tubes. These tubes not only sound harmonically richer, they seem to last forever. Life is short. If you can get good ones, it's the only way to go. They inspire.

Try to put the tubes 6N23P, 6N23P-EV (ECC88, E88CC, 6DJ8, 6922) through the adapters for 6N2P.

The "S" in the Sovtek 12AX7LPS stands for spiral. Spiral filament for lower noise.
