My expirience with the Emotive Audio Sira LE is same. I switch to the Tung Sol 5687 and got some microphonic noise, especially when touching the volume or the preamp. Well, I like the sound of the Tung Sol 5687 better so the "ring" thing doesn't matter to me. When the music plays, that's what's count.
Tube Whine noise...Please Help
Hi everyone.
As a newbe to tubes I am having a problem that I need some help on. I just received my Musical Design SP-2 preamp and while it sounds wonderful, occationally there is a high frequency whine/whistling noise coming from one or both speakers. The SP-2 uses 2 6922 that the previous owners said were NOS RCA types. I want to know if the tubes went bad and needs replacing or if there is another problem that I need to look for. Thanks
