I need to replace my E34 tube on my Audio Aero Amp

I bought an Audio Aero Capitole amp on audiogon and recently I noticed quite the, for lack of a better description, feedback noise that would happen in my right channel shortly after powering up the amp.

I tried trading tubes from the left channel to the right and after much experimentation, I have isolated the problem to the E34 tube.

these are the tubes that came with the amp. They are 'JJs".

Question: are there better tubes? Can I use other brands or should I just stick with the same replacements?

Any suggestions, and a name of a distributor are appreciated.

thanks.

Infinitebaffle is correct. I had been using the 'new' Svetlana's, recently switched to the SED's, harmonically richer, more transparent. SED's are the way to go.

I agree with most of the above. Don't buy the current Svetlana/Sovteks. The "Winged C" brand Svetlanas are really good, especially if cryo'ed. I love the sound of NOS Mullards and Telefunkens, but the current asking prices are way too high! If you can find NOS RCA EL34s, get them. The "fat bottle" Ei EL34s (6CA7s) are a nice tube at a very reasonable price too.

My Goodness;

I was wondering if I would b getting any replys at all...

This morning there were the first two. So, based on these, I put a call into Darryl at Digital Systems who is the Audio Aero factory approved repair-man.

He suggested Svetlana, but urged me to stay away from Sovtec.
I am hoping for a few more replys here but it looks like I am ready to take some copious notes and get myself on the phone.
More to discover
