I could help you, as I have the schematics on my home-pc but not here on my office pc.

I got it directly from Classé Canada, they are very friendly.

When you don't want to contact them, you can send me a mail to franz dot gysi at tiscalinet dot ch.

Kind regards
Franz

P.S.

When it not already went up in smoke, I strongly recommend to add separate fuses for ALL voltages and replace the critical electrolytic caps! Some electrolytic caps in this player tend to shorten, resulting in a completely burned pcb!

I'll second that. I asked Classe for some (partial) schematics a year or two ago and they mailed them to me w/in just a couple days.

... and adequately for your devices serial number, for the correct revision-level.

And: they offered me to contact the engineers, should I have questions.

They remarked: this device is quite old.

Have a look at the foto in my burned pcb: I strongly recommend to replace all caps of the same type like C404 and C407 and to add the mentioned additional fuses. A working DAC with PMD100 and this famous DAC monolytic hybrid chips are worth it!

Kind regards
Franz
