Just a heads up. Been working with thetragichero on this. He redid the power supply and added a ic regulator to supply the 24 volts for the preamps. This amp has been "worked" on by someone else before and they mangled it. In addition.to out of tolerance resistors, incorrect parts put in in the wrong places, the 1N3754 was substituted and just hanging in mid air. He will be checking the rest of the diodes and transistors tomorrow along with the rest of the resistors. Steve he has a couple of messages in queue that is why I put this up to let you guys know where we were at.

It was in fact a 602 board in the amp. Someone tried to "rewire" it to make it work for the 24 volt supply.

Time to put these east coast eyes to bed.

Oh yeah, it actually is a K200A-1 amp with no effects just like the one I have, so it has no need for -24.
