Power requirements: +/-25 volts dc, 20mA nominal, 80mA maximum

Peeping the module plan, it is very slightly voltage-sensitive. +/-24V will be fine. +/-18V should work fine. +/-12V gives up headroom and also gets you into a trace of crossover distortion (WBS biased output pairs with resistors instead of diodes).

By the specs, you "could" need 2*80mA = 160mA for a pair. But that could only happen with 600R load on the Insert and a totally-clipped signal. I can't see how even "normal overload" could ever exceed 100mA/pair.

A +/-24V 100mA supply should be easy to turn up.

 PRR  thanks for replying.....  I have the W625B, I just need the pinouts off the psu connectors on the back to get some type of cable(IEC?) with male/female to mate and connect those leads to elco's inside of rack case of pre's.  Did that make sense???

There is a 485 +/-25V supply at the URL I posted. Does its connector look anything like yours?

I am a member of that forum.  No, there is no picture of the connector there, at least that I could find.......The amphenol connectors on the back are labeled P1 and P2.  One side is for 110ac and the other is for P48 and lights.  That's all I have grasped thus far.  PRR thanks for your help and I really appreciate any facts you can find for me.
