A quad of these were installed in a Peavy Windsor amp I had a few years ago and I thought the amp sounded good, especially for the price, and I thought the EL34B tubes installed in it sounded very good. Chinese Tube manufacturing seems to copy a lot of the old Japanese products - from Matsushita and Hitachi, and the EL34B Chinese its a perfect example of that. I have several pairs of Japanese "Mullard" EL34 tubes and these are a good facsimile. Like Groove Tubes I am generally impressed with TAD products

Got a set of four of these Tube Amp Doctor-EL34B's on a recommendation from Rivera Amplification. Yes. Just what the Dr. ordered, no pun intended. Worked perfectly, packed thoughtfully, and shipped immediately. What else is there to say?

I've always been a fan of the TAD products. Used their 6L6's in my Pro Reverb and did some amps for other guys using their EL34's and a full set in a friends Bassman 50 head...

Anyway, These sound great, biased out quite well (set them at about 35.5mV) and so far have done great. I don't have many hours on this set yet but I expect them to have good longevity if they are anything like their other tubes.

I took the advice from TGP and ordered these for my Fuchs Modded Music Man ODS. This thing completely came alive compared to the JJs in it before. Muddy was gone. Shrill was gone. Lots of body/depth in the sound profile. Amp sounds great at any volume now.

I researched for days to find an EL34 tube for my Bogner amp. What I love about TAD tubes is all of the testing they do to make sure they're 100%. I had JJ EL34L and JJEL34 tubes installed prior and there's no comparison to the TAD's. Build quality and sound make these a no brainier. I don't understand when someone has an expensive amp and want to save a few dollars on some cheap crappy tubes. You definitely get what you pay for when it comes to tubes.
