Is this right??

[3nity]

Im racking some Mccurdy eqs for a friend.
I dont have any documentation other that they run on +/- 25V.
For now i traced the Ins/Outs, so thats OK.

Whats a bit challenging its finding the V+ and V- pins...GND its obvious.

Those EQs are full of NE5534s and TL072.
Should i assume that its Right to reverse/trace the V+ from the NE5534 Pin #7?? and V- from Ne5534 on Pin #4??
Should i get the right connection based on this way of working??

Thanks

Yep!

25+/- Seems high for ne5534s....

Well they have on board regulation...
As soon as you said yes i powered them and measure +/- 20V at respective pins.
Thanks.

Unless I misunderstood the question, I would use a multimeter
