Good Afternoon, Steve:
We have a little fun on this site from time to time. Big Mike lives in Missouri, I live in Tennessee, we've met, we're good friends, and God will get him for his crack about my moniker. LOL
Well, if you are adept enough at getting the amplifier out of the case then you are serious about repairing the unit.
My first recommendation is that you pick up a diagram on the unit. For that, I always recommend Sams Photofacts. The information includes schematics, parts layout, parts identification, test information, and part numbers for everything. You can check them out at
http://www.samswebsite.com/photofacts.html
Getting parts can be a chore. I have had some success with Union Electronics on-line at http://www.unionel.com
For one, they sell individual piece parts to consumers. Another is a smaller operation in New Jersey called Lashen Electronics and they are at http://www.lashen.com/
Tracking down the smoked parts will require a decent
volt-ohmmeter which you can get at either Lashen or Radio Shack. On the final amps you will need to read continuity
between emitter-base, collector-base, and emitter-collector
to determine what has shorted, etc. The Sams Photofacts will help you find the individual components and surrounding circuitry.
If this makes any sense to you, come back and we will discuss it more in depth.

thanks for your help i do want to fix the stereo but im going to be gone next couple of days. i did do a quick search last night and found the amp part for $55. does that sound right. would each device come on and play (with no sound) if the power supply was bad? i hate to replace the part $55 if im wrong. you know what, im going to get a picture of it and get back with you. see ya.........

What's that smell? Smoke? Nawwwww :) Boy smokey's gonna get me:) Actually the amp would have needed to be checked in circuit. The schematic is a must for a novice, or even me. I like to have the paper there even if I know how it works. That's a pretty good price on that amp! Another place for things like this is http://www.tritronicsinc.com/ I have used these people for years, they stand by their product and have a large selection of product. Tape to TV's. Anyway need to open the windows... Man am I gonna get it:)
