hey. i have the same amp with the same amp with the same problem. i got
it fixed but it broke again. i've had a lokk and i can't see where it
was repaired. i do have some info if any one can decipher what it might
mean;
1.there is power coming from the transformer
2.the speaker works
3.i cant see any thing missing inside
4. the only way to make noise is to turn it off and i get the fade-out.
with different settings the fade-out is different so the amp models
work.
