I've eventually tracked down a fault in my Fender Frontman 15R, to the Bass tone potentiometer. Here in the UK parts like that seem to be hard to find. Does anyone know of a USA source, or, failing that, would it be possible to bridge the faulty pot out altogether. At least then I would be able to use the amp.
The current pot (which I've removed), bears the number 30C250K
Thanks.

Hi!, my Frontman 15R had been working ok until 2 days ago. On switching it on then, it immediatly started to howl extremely loudly. Even setting all the knobs to zero and unplugging the guitar made no difference at all. I'm comfortable with repairing most elecrtical items but electronics is a grey area for me. I've removed the circuit board but cannot see any obviously faulty components or dry joints. I guess the amp is "dead in the water" given that they are fairly cheap to buy. I just wondered if there was anything I could try to trace the fault as the amp is otherwise ok. Thanks.
