Default Mark Levinson ML1 Preamp Schematic


A friend of mine has an ML1 with a couple of faults and I'm trying to help him out. Has anyone got a schematic? From what I understand, diagrams for the contents of the potted modules are hard to come by. If you don't have a full diagram, a service manual would be helpful.

I can trace the thing out with oscillator + 'scope probe, but a manual / schematic would save a lot of time.

Many thanks in advance.

I understand from various threads on diyaudio that the ML1 is derived from the JC2 that was designed by John Curl. There are various threads here discussing the JC2. However you may already know that.

You will find schematics for the jc2 here and on the internet and unless John Curl or someone else can help that may be as close as you will get.
