Denon POA 6600A schematics

[musinteg]

HI all, I'm in desperate need of schematics for a Denon POA 6600A.

Currently, I can get it to fire up by cheating ( I jumpered the power relay, but have the amp plugged into a VDR ( voltage dependent resistor----60 watt lightbulb ) powered outlet.

It is latching up to the top rail. Have checked all my outputs ( new ones ) pre drivers, fuseable resistors, diodes, etc...and nothing ( I'm a 25 year Audio tech ).....so this one has me a little stumped.

Any help would be appreciated.

I specialize in Carver, Adcom, Aragon-Mondial, pro gear and recording studio equipment ( I LOVE the old 2" analog tape machines ), so if anyone needs help, I will be glad to.

Thanks

Rob

I have used TAC for several years and contributed. Those are for a 6600. The 6600 is a normal amp, the 6600A used " optical class A " .....basically an optocoupler in the driver stage. The problem is in there somewhere.

Thanks anyways !!
