Just came in and was only drawing .56amps of current, stuck in protection. All the buz272/buz21 check good. Power supply is good. So I found a few driver transistors were missing from the board. I replaced them and now it draws 1.81amps of current and rear channel are working and the front does not unless in 2channel mode I get a crazy looking signal only on the fleft.

That's what it was I backed them all down a quarter turn. It only goes up to 2.85amps when I push the 5v 40hrtz tone into the front side. The rear two channels I don't have the signal on the two 10ohm resistors or anywhere past u40, it goes up to the switches but not to the output transistors.
