pb with PMA 560

[ericb]

hi ,

I have some pb with my PMA 560 : i think that one pré-amp channel is down
When " source direct " is on the amplifier is ok . ( it is the same with CD or AUx )
Someone can help me ? ( a schema or help for diagnostic ?)
Sorry for my english.
éric .

Simplest thing to do first - check the source direct switch doesnt have broken contacts.

PMA 560 - too hot

hi all,

I feel that my old Denon PMA 560 is over heat. I've check the transistors - ok. Does any body know the rule to adjust the trimpotensiometers in the amplifier module.
