I've just been converting my stereo gainclone to a dual mono gainclone while building it into a new case and when turned on the transformer 'growls' (the best way I can describe it). I have to say i'm no expert on transformer noises so it could just be a (very) loud hum, although it does sound quite deep hence the growl.
The reason I suspect it is the grounding is because both channels work perfectly fine if the other is disconnected. I just want to make sure this is it before I do some kind of other damage or change things that are perfectly ok!
A few bits of info that may help;
-It's the chipamp.com 3886 kits
-240V primary, dual 22V secondaries. I think it is around 200VA
-All in a single case with single ground for chassis and two amplifier boards
-Mains passes through fuse (hot only) and dpst switch
Thanks in advance
