Replacement chinese T-amp arrived. This one works. Rather it functions. But it really is a piece of shit. Loads of hiss and some really hard ultrasonic or high treble energy which gives me a headache no matter what I attatch to it.
Tone controls are awful.
Might be able to cure some of this by modding it a bit. Replace the input op-amp, bypass the bass and treble dials, put in some better caps etc. Just not sure if it's worth the bother even if I had the time.
Newest version of the one to be found talked about here.
