Need advice on Glensound / AM22 EQ repair and power supply.

[andersounds]

Friend has dropped off an EMI / Glensound / BBC, not sure exactly who made this thing am22/15 EQ, stereo unit transformer in and out, needs some work done on it, but I can't locate any schematics, from the details I have been able to find I think it needs a -24v power rail for the NPN germaniums?

Does anyone have any experience or useful info on getting one of these classic BBC EQ's going?

Any help would be great.

I owned one of those for years.
I bet Mike Rippe at analog audio repair could fix it up for you... or at least help you out. He is located in my studio, in the tech room...

Check with him. I liked the compressor on that box, and I am sad I ever got rid of mine.

It was made by Glensound. The EQ's are okay, but the compressor section is really quite good.

I have found out more info on this unit, as it has been rehoused in a different box turns out it is an EMI AM22/2 stereo eq as here:

thanks for your help I'll send an email and see if he has any insights on the power requirements I'm assuming now a -12v rail.

I thought most Glensound stuff ran at -15V, but since those were from weird EMI broadcast desks I'm not confident how it would be powered. I've seen a couple people try to pawn them off for ridiculous prices too since they say EMI on them.
