Octal power tube (Max Plate Watts = 25W)

Sensational new high-gain EL34 tube with a very dynamic tone. An authentic remake of the British Mullard EL34. The clear and harmonic open top end allows for great clean tone and at the same time the TAD EL34B-STR offers incredibly powerful mids and equally powerful bass. The golden control grid and especially large cooling grids guarantee maximum stability and reliability. Consequently, this EL34 provides a maximum of gain and dynamic response.

Can replace any 6CA7 or KT77.

Q: When does a power tube become a Premium Selected power tube?
A: All power tubes labeled Premium Selected have passed the following tests:
- Plate Current (PC) and Amplification (TC)
- Low Noise Test
- Microphonic Test
- Sonic Tests
- Shock Tests
- Listening Tests
- Shorts & Leakage Tests

I think I found my new go to place for tubes and electronic components. Order was spot on....shipping was quick and secure. Both sets of tubes arrived safe and sound......this does not always happen from other laces.

These TAD-EL34B-STR Tubes are everything people have told me!Bigger glass and plates for reliability and heat dissipation! Big clean headroom and huge powerful gain! With the Ruby 12AX7AC5+ V1 and C7 in V2, My Blackstar HT 60 Soloist be Rockin the House! Thanks Wesley for all your help!

Lately TAD’s tube matching seems to be hit or really miss. I’ve had a pair of these and another pair of WGC’s that were 15 mA apart, regardless of placement in either amp! The tubes themselves are ok, once you match up a pair.

These are great power tubes, it's hard to say just what made this amp this time. I did put the jj 12ax7 long plates and it softens some of that tsl 122 fizz they are noted for. It growls like a marshall should and the clean channel is crisp and loaded with clear mids and bottom presence. I am glad i ordered from Antique Electronic Supply, the EL34B TAD's were excellent and easy to bias and really round out the sound of the Marshall JCM TSL 122 iike no other tube i've had. Worth the little extra dough

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.
