Rowland Consumate Phono amp PSU

[bigecho]

Hello folks,

I have a Rowland Research Consummate Phono Amp but without the original amp and PSU.

All I know is the phono amp should be powered by DC +/-22V.

Does anyone has the "pin assignment" of the original PSU output connector as the attached picture.

Many thanks in advance! 🙂

Open it up, trace the circuit back from one of the pins to the first polarised component you fine, capacitor, diode, silicon chip etc and you will have your answer.

Thanks for the tips. I did that already and just found one supply line going into a potted module, so wasn't sure if it's plus or minus.
