Hi!
I recently acquired an old RFZ W760/2 MS matrix mixer without any pin-out documentation, that I would like to get up-and-running.
Beforer i start experimenting - if anyone knows (or has a qualified guess) which supply voltage(s) these units operate at, it would be a great help (....I suppose asking for a schematic is wishful thinking...).
Basically, the unit is a Danner-like casette equipped with a 2X13 pin Tuchsel connector, where 2 pins are supply voltage lines. They each feed their separate PCB (i.e. the two supply-pins run to different PCBs). Other connections are 2X in/out and ground.
The unit is fully discrete, only caps, resistors and transistors on board.
