Hello all.
I got the speaker amp part of this combo for 69$ at a pawn shop. I got it home and found that the output protection had tripped (what a surprise!).
It has lots of nice parts (japanese transistors), a HUGE trafo, a HUGE heatsink, a SMALL heatsink, and lots of even smaller heatsinks.
I suspect that only one amp is broken, while all the others are good.
I imagine I could part it out and make a good amplifier with the parts, but I don't want to leave the front end dangling. It seems simple enough to simply replace the amp parts and hook it up to the output protection and other parts. Yet, the amp has .8% THD and I don't know how much of this is in the output amplifiers and what part is actually the front end circuitry.
I guess my best bet is to replace all of the audio frontend but leave the video in there. But that can get even more complicated.
Should I repair it and sell it, rebuild it and use it, or use its innards for other projects?

Definitely worth repairing keantoken, have jou seen the update/repair of Nelson Pass on the Harmon Kardon? This amplifier is a collectors item I believe.

Well I don't have the remote, just the main amp box.
lots of nice features. But distortion is .05-.8% - I am more ready to say this is because of bad design rather than someone actually trying to make it sound good.
I will search for what you are talking about and see what's up.
