Hi chipper - if you know electronics and how to solder what you most likely need to do is to replace the variable resistor (Potentiometer - http://en.wikipedia.org/wiki/Potentiometer ) that adjust the gain of the amp. Yeah - a broken pot could cause the amp to make loud screeching noises - but check your source material 1st - could just be what's playing.
 If you don't know electronics then this link might help - http://www.bcae1.com/ OR - find a repair tech that owes you a favor. Good Luck!
