Mark Levinson 436 schematic or detailed photos of circuit NEEDED

[edkiwi]

Please help. Hi all I am trying to get some Mark Levinson 436 schematics as mine are no good and they are impossible to find. Please someone help. @levinson mark or @Hans Polak I hope that you may be able to help? If not some detailed photos of the circuit with numbers would be a lifesaver. Thank you

What part are you looking for, voltage amp, current amp, power supply or what ?
And what is the problem with your amp that you are looking for schematics.
Here are some pictures to start with.

Wow! Those boards are getting cooked.

Hi thank you. You can see my board has been fried. I put in a minidsp preamp and had limiter on but it fried it ( you can see burns on my photo). I am also having trouble taking this out. How close is the 436 to the 434. Can I use schematic plus photos for comparisons?

I’m sorry by not fully understanding what you mentioned about a minidsp and limiter.
Without any external connection, what output voltage does the amp show?
And what are the voltages on the input XLR plug with reference to ground.

The 434 and 436 voltage gain boards are indentical with only some different resistor values.
