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.

Now it's time to learn tube rolling! All EL34's sound different. Personally, I feel that vintage Mullards are best followed by telefunken. NOS Siemans can be nice too and a little less money. I agree with infinitebaffle about svetlana's. The Shuguangs are nice but a little too "soft/laid back". I got my hands on some NOS Groove tubes and am amazed. Older US made EL34's can be great.
You need to decide on what means most to you: detail, cranking rock, tubey sound, just plain accurate, bright.... and then start looking.
Try:
upscaleaudio.com, tubesandmore.com, jeffssoundvalues.com, thetubestore.com, tubeworld.com(just to window shop-too pricey).
