How old is it? Date codes on the pots and transformers ought to tell.

Andy Ross is the son of Bud Ross, the man who started Kustom. Kustom and Ross are long parted, but you could contact Kustom and ask.

But I see no amplifiers there.


What is wrong with it? Problems are often generic. Power amp, preamp, power supply, interconnections. A very common problem in amps is dirty jack cutout contacts in things like FX returns and power amp in jacks. and any amp with a headphones jack can have problems with it turning off the speakers.

Chip amp? DC on output? Bad IC. Touch input pin with something, hum comes out speaker? OK. No sound? Bad IC.


Preamps, usually start with power supply, then look for unwanted DC on output pins of op amps.
