Hi !
I own a CM912A, that was defective when I got it. I had to reverse engineer it to have a schematic to work from. I could send you a copy if you are interested. For your information, it puts out around 180 Watts into 8 ohms, and should provide almost the double into 4 ohms considering the size of the power transformer and filter capacitors, but I haven't measured that.
On the other hand, the wires that go from the feedback Cinch-Jones connectors to the amp PCBs were removed at some point, and I would like to reconnect them. On the PCBs you can see what's left of 3 wires, a white one, a grey one and a green one, but I don't know what pins they go to on the Cinch-Jones connector. If you still own the amplifier, would you be kind enough to send me a picture of that connector so I can identify the pins?
