[sdiy] Need help about how to service an amp

[Jean Bender]

Hi list !

A friend gave me a Peavey KB100, not working, i mean it's powering up but
no sound, even in the headphone output.

Well, i realise in don't know from where to start when you have to service
an amp. Is there a specific way to work once you have check all the basics
(fuses, power supply, and visual check up around caps and chips) ?

Do i need, for example to simulate the speaker impedance if i disconnect it
from the board for troubleshooting the circuit ?

So this thread is more to have tips, readings about this kind of thing,
since i don't feel really comfortable working on it from scratch knowledge !

Thanks per advance
J.
