Thanks a lot for any help.

Revox B 226 uses CDM 1 - 100% sure
Studer 727 used CDM 2 - 90% sure

Don't know about CD 95
CD 94MKII used CDM 1 too but CD 95 was a bit diffrent line.

I think Revox srvice manuals are somewhere in the internet,they should also help.

Hi,

Got it downloaded, but winzip complains it is not a valid archive
Could you have a look at it?

mmm, looking at the name of the pic, it must be from the 226.

hmm,could be a wrong picture.The manual depicts a different setup.

No. Revox B226, Studer A725 and A727 all use the same CDM1 - 100% sure.

It's pretty much identical to the one in my A727. Also used in Revox B226, as you can see on the attached clip from the service manual.
