tube pre-amp feedback...


I have recently switched from a solid state pre to a tube pre with my Odyssey Stratus amp. Now while I like the sound and combination, the EAR 834L pre I am currently using does seem to cause some feedback/light buzzing. I find this the most when the volume is all the way down, becoming quieter as I turn the volume up (yes, even when I don't have anything playing). I also find it sounds like something in the line is picking up a radio frequency or something.

This seems strange to me, as I know the person I purchased the EAR from used it with a Bryston. I'm a tube novice looking for advice. Any thoughts appreciated. Thanks!

If you're sure about radio freequency than I assume the preamp tubes very often can pick up even a voice or will do the noise even if you blow on them.
The tube dampers and coolers sold from Michael Percy www.percyaudio.com can work-out for you in that case. Make sure that space in preamp allowes you to "dress" tubes.
