Thanks all, I haven't opened up again yet.  I realize I have some perfect wire for that repair.  Now a local guy wants to get it from me to fool with it (or maybe make it into a non-powered stage monitor) I might let him buy it.  I'll let you know if I go back in.  I'm a little afraid of taking out that TDA7294.  I guess I'll need a more pointy tip for my soldering iron.

One other question. I have a little peavey kb1 that I'm going to use as a powered monitor is there a merit in using this (now semi-famous) speaker, in the peavey?  Both are 4 ohm.

I'll let you know what happens after I hear from this guy.

Be very careful when pulling that TDA7294 (or any other multi pin chipamp).
Melting solder and wiggling the leg will very probasbly tear the pad off.
You need a hot clean solder tip, a *good* solder pump to suck 90% of solder, then finish with solder wick.
You must be able to pull chipamp legs *easily*.
You can buy a new chipamp fpr a few dollars, you cannot buy a new PCB, so some prefer to just cut all lega, throw the "body" in the junkbin and pull leg by leg, with longnose pliers and melting solder one by obe.
The message is: pamper the  PCB.
