Q for Brian Roth RE: ADM 770

Hi Brian,

I've had a pair of ADM 770's here for a couple of years that I've meaning to rack up. They came with a pair of (I think) Slidex faders Model 485. The faders have a 9 pin connector.

I finally have the +/- 20v, 24v, 48v power supply worked out,. but I am stumped at the faders. I have the schematics at http://vintageproaudio.com. but they are extremely hard to read. I really want to dispose of the Slidex faders and use rotary pots (5k I think) as the level control instead of the Slidex faders. Do you have a pin out of the fader connector? I've stared at the damn schematic for what seems like hours but I can't make heads or tails of it.


Thanks,

elco

P.S. I also posted this at your old stomping ground at the gearslutz as I'm not sure you are still active there.
edit: I just saw that you are still active there. My bad.

ADM used a 10K *linear taper* pot in the Slidex, and obtained a quasi-audio taper by virtue of the 2K7 "slug" resistor from wiper to ground.
