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.

Nick

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.

This is an older thread, but nickbfl, do you still have those schematics? I've got a No. 27 that has a bad channel as well and they would be helpful.

Hey thanks guys. Schematics for the 27 seem to be hard to come by. Hopefully, this will help.

The channel is not dead but the volume is very low, if someone had the same problem, I would appreciate some tips.

Thanks
