buyer beware

I do repairs for a local pawn shop, the owner called me and asked if I could pick up and amp and check it out for him.  I get there and ask what it is doing or not doing that makes them think it is broken?  The salesman replies with "The old grey mule just ain't doin what I know she should be doin.  I take the amp from him and immediately notice the lack of weight.  I think boy is this going to be good.  I get it to the shop and put it on the bench and notice right away that it is just as I suspected, a chip amp.  Meaning that it has an output chip just like a radio.  Max 18 watts a channel.  It is working just as it should, for a chip amp that is.  I have seen many 14 inch amps with 8 inch circuit boards inside them.  I almost did not remove the cover from this jewel.  I am glad I did.   This amp was about 20 inches long.  As you can see in the top picture, it is rated at 1600 watts.  It has a single 40 amp fuse on the end.

When I removed the bottom cover, I was expecting similar, but there was way less than I expected to see.

The following pic is of the actual amplifier board.

looks like the inside of a "walkman". waaayyy long ago before the days of portable MP3 players, lol.
