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.

I am not familiar with E34 tubes, but I recently bought a matched pair of JJ 300B from http://thetubestore.com and I was very pleased with their selection and quality of delivery. They have a prety good veriety of EL34 tubes, and acoording to the link below EL34 and E34L are of the same type

I hope this helps a little.

I personally like the JJ tubes, but there are just as many out here who prefer the Svetlana. The two have different sounds, it's a question as to which are more suited to you.

Svetlana are warmer and sunnier, JJ are more forward and open. Both are excellent so you really can't lose. I don't know what EH sound like, but you'll probably have some recommend those as well.

The current production Svetlana branded tube is not a real Svetlana. It is made by Sovtek and is not very good. The original Svetlana factory is now selling under the name SED with a Winged C logo. This is a great EL34-E34L. Almost as good as some of the very expensive NOS tubes. I think it is considerably better than the JJ version. Again, the real Svetlana tubes are now branded SED-Winged C
