Denon D-f07 Service Manual and Questions

[lectrolux]

Hi
Ive got a denon system D-f 07 I want to roll a few op amps in, the cd is straight forward but ill need a service manual for the amp.

If anyone has a service manual for it or a link to a free copy I would be most greatful.

Also a few questions too.

1./ All units in this system plug into the tuner and the tuner plugs into the mains. Can i plug the amp straight into the mains ( i have a plug to adapt it from two pin plug to uk threee pin) or will that cause a problem.

2./ When i was testing some opamps in the cd I noticed the pcb board darken slightly near the power supply and thought that this might be related to the power supply( hence question 1) as I plugged it into the mains.
Also it was the same time I had put in some ne5532 opamps in, which iirc can produce some kind of feed back to the power supply (ive got no idea what im talking about but roughly understood the info) and maybe that caused the blackning on the pcb.

Thx all for help
