I have a FM212R with a non-working clean channel. I have the schematic for the 61536000 board but can't find anything for the 61535000 board. The circuit is different and I don't want to draw out what I have ( will take me forever) if someone has the correct schematic. Thanks for any help.

What sort of differences. The only drawings I ever saw were for 6000 drawings. Both A and B revision levels.Education is what you're left with after you have forgotten what you have learned. -
My board is rev A. The circuit around Q5 doesn't match the 6000 schematic. I thought Q5 wasn't switching so I started looking at that part of the circuit. Q5 goes to the anode of D9, same as the 6000 schematic but the cathode of D9 does not go to the junction of C10/R18 as the 6000 schematic shows. It connects to D11 attached to Q3 and D14, attached to Q4 which sort of makes sense. I know basic electronics and can make my way around a simple amplifier circuit but have little experience with circuits that use JFETS for switches. This one has a bunch of them.Comment

Sorry, should have included - the 6000 schematic I have is a rev A.Comment

Have you looked at the FM65R schem? (attached)
The component names may be different, but it sounds like it might match what you are describing. And the drawing # ends with 5000.

Yes, I doubt the 6000 board matches the 6000 schematic at Q5 either. Looking at Q5, I can't see it functioning as drawn.
The circuit in FM65 looks like it makes sense. The circuit in the FM210R looks like the FM65 in that regard.Education is what you're left with after you have forgotten what you have learned.Comment

Thank you gentlemen, I'll give the FM65 schematic a try.Comment
