thanks omaro,
if you can send a copy to my address email, you would make a large favor me.
I hope to resolve the breakdown. All it is begun with the relais of the protection circuit that takes part, then have gotten out of order the output final transistors, (with resistances) of feeding.

thanks again,

defender110.

Omaro, just got a A-720 with one weak channel.
I was wondering if I could get a copy of the schematic.
So far some brown glue used in the center of the
circuit board appears to have corroded leads on
some parts there.
Have replaced 100 MF 25V caps and a 820K resistor.
Not sure what else may have been damaged by this.

I see http://www.audio-circuit.dk/ is down for now.

Yamaha site does not have A-720.
