I have been trying to repair my Mark Levinson 383 for some time now without success, and I haven't been able to find a repair manual anywhere.
Would anyone be able to help me out with a copy of a Mark Levinson 383 service/repair manual?

Hello everyone,
I am trying to repair my Mark Levinson 383 and I have an issue I need help with.
When I power on the amp it goes into protection I think. The amp does not boot up. I hear the relay on the fuse board click, but nothing further. The led on the control board blinks once and then three times. I don't know what it is trying to tell me. The amp did power all the way up prior to this.
Any thoughts or suggests would be appreciated as to what could be causing this and how to troubleshoot the issue.
Thank you.

There is no service manual for 383 ML No33 and ML33H Mono blocks only PDF schematics.
There is 23 PDF schematics for ML-383 Int amp. There is also an update.
Replace the 25000uF/90V power supply cap/10000uF/16V just 1 cap .1uF 200V cap. Check the VG board for any burnt resistors or caps.

Hi, did you ever get the schematic of the ML383? I am also trying to fix mine because it makes a loud pop in the speakers when you turn it on and sometimes there is some noise comming from the right channel.
I think it is a noisy transistor. But it sure would be helpfull if I had a schematic and after searching for 2 days I'm hoping that someone has them? Please?
