ADCOM GFP 555II schematic/service manual

[gm_gm]

Hi,

I'm looking for a layout, schematic and/or service manual for a Adcom GFP 555II Preamp.

my preamp has a little problem.
If i switch the record selector on the same source as the listening selector the signal of the right channel breaks down.
The effect depends on the volume.

My service could not find any solution and there is no Adcom support around (Germany ;-) )

If anybody has a schematic and/or service manual, please email!!

Grüße

There are many guys that sell it on ebay. One seller's ID is techman777. I get lots of Adcom manuals from him.

infact he has one on right now:
