Hello, would anyone have the manual service of the Marantz PM94 US because the manual service on hifiengine has a huge error.
I read on a forum that there is another complete manual with a white cover .

Have you by any chance been able to source the US service manual? I am looking into adjusting the settings on my Marantz PM 94
Perhaps I'm overlooking something, but the first step of the idling adjustment procedure appears to be incomplete. Step 3 namely mentions R642 and R742. Do I need to put these 10K resistors in circuit in step 1?

Not sure.what the huge error would be. My experience is that you ways need to check the values of listed parts like capacitors to the values in the schematics.
My issue is that the adjustment procedure isn't clear to me. Perhaps someone can shed a light on this?
Also, I have done a full recap apart from the filter caps. Should I check/ readjust the bias? Reason I"m asking is that the left side feels warmer than the right side of the amp. If so, should I first replace or clean the pots?
