I have this preamp on my bench for repair. Without a schematic or users manual I am helplessly floundering around looking for some indication of what is wrong. It appears the mute function is constantly turned on and consequently I get nothing out of either channel under any circumstance.
Internal inspection showed signs that someone had been there before me so who knows. Impressive internals and box. There must be 100 ss relays in this thing. The input relays seem to function properly since it properly selects the input channel and the signal makes it to the main board and then to what I suspect are volume control attenuators. These are labeled as mercury wetted relays. The signal never makes it out of these boards on either channel.
I have read some high praise of this preamp and would really like to hear it in my system and be able to please a hopeful customer at the same time.
Does anyone have experience with this preamp?
A schematic would be an incredible advantage and greatly appreciated if anybody has one. Operating instructions might help as well.
