Delco-Bose Part# 16160111, chevy amplifier fix.

[Steel]

Hey guys. My Z34 has the delco-bose amplifier in the trunk that runs all of the speakers. Right now, its popping and crackling and all that jive, which is i guess pretty common when those amps get old. My only options are to track one down from a boneyard, which is always hit or miss anyway, pay 280 bucks for a 'new' one, or pay 200 bucks to send it out and get it fixed. Screw that. I know i could fix it myself, but i just need to be led in the right direction, such as which wires to resolder, which resistors to replace, ect. If anyone knows how to fix these, and/or has a wiring diagram, that would be greatly appreciated.

Thanks guys.

open it up and look for obvious fried transistor's. Even smelling them sometimes works. Or leave it hooked up, open it, and turn it on and feel them. Usually bad ones will get really really hot within a few minutes. Otherwise get a digital multimeter, set it to diode test, and probe each leg of each transistor backwords and forwards, and then move to the other leg. This involves about 6 different tests on each transistor, and if you get a reading thats close to 000 or 010 or anything that settles down really low, it could be bad. Also they could be bad if they have very high resistance. Once you find one that seems bad, unsolder it and check it again, if it still looks bad, replace it. You can usually get parts a mouser.com or electronicsic.com pretty reasonable. Not much else to tell ya here, if you dont understand what I just told you , look up transistor testing with a digital multimeter and familiarize yourself with it. If you still dont want to try to repair it, I have a few amps laying around for friends that need parts ordered for to be repaired, if you want me to take a stab at it, let me know. Good luck.
