Default Mark Levinson No 27 -schematic requites

I have a problem with one channel of a ML No 27.

If someone has schematics, service manual and/or PCB layouts (note No. 27 not 27.5 as they are rather different) that they could share I would appreciate it very much.

Thank you very much.

Please include me if you have the service manual for the ML No.27 I don't have any problems but it would be very nice to have it and I'll cover all reasonable costs for copying, your time etc. by PayPal or USPS money order. Many thanks, Mike.

Default Did anyone ever track down Mark Levinson No.27 schematics?

I have exactly the same problem. One channel no longer outputting bass. Did anyone ever track down the No.27 schematics?

The channel was completely dead. The problem was a shorted film cap. I can't recall more than.

I do have a set of schematics that I made of this version that do have a few small errors if anyone wants them, pm me.
