ML-9 schema (pdf)

Hello everyone,

I still have one of these, if you can follow this link (my own G Drive). I can't say if the schema contains everything needed ?

Please tell me if you can reach the doc that way or if I have to put the pdf somewhere else (or send it by email...).

Best,

Is not a confusion with Jeff Rowland M-9 ?
Look this is a clone of China :

Hello Dear Friends!
Please help me!!!
My loving vintage power amplifier Mark Levinson ML-9 is under repair, diodes are broken there!
There is no way to see their markings.
Could you send me the marking of these diodes!

I hope for your assistance and support!!!

Do you still need those numbers?
Can you post a complete board pic please.
There at least 3 board versions.
