Fellow Stax mafiosos,
I need your help. Yesterday I noticed, for the first time, a very, very low humming noise coming from my modified T1. This starts as soon as I hit the pre-heat button and without any source feeding the amp. To make things clear: the noise comes from the amp and is audible when sitting next to it (1-2 ft)!
This is very odd, what could be the cause of this problem?
Thanks in advance for any help...
Edit: it's a slight, not easily audible noise. I still cannot tell with certainity from where it comes exactly, but it's definitely the amp itself. It doesn't seem to effect sound quality when I listen with my Lambda Signatures.
Could be that one of your tubes is going bad.
