Title: Here are schematics for ADR Gemini Easy Rider compressor.

Thanks to Niko, who kindly posted me photocopies of these diagrams, here are the circuits for the ADR Gemini compressor.

http://homepage.mac.com/agenttriez/

I got one recently, as I use an ADR Vocal Stresser all the time, and I hope that this will have a similar character, but stereo. It is an all discrete FET design, the only chips in the unit are the meter drivers. I haven't heard it properly yet as it needs some service, currently the left and right channels are uneven, but a re-cap, re-trimpot and some new pots and a calibration should see to that. Oddly enough for ADR it is unbalanced, but if it sounds good I will soon fix that!

I haven't posted the PCB layout, it looks a little busy to reproduce well, lots of stuff overlayed onto it, but the PCB is silkscreened, so anyone servicing one shouldn't have a problem. The schematic shows 1 of 2 channels, each channel has identical component numbers/designations.

Wow,

Thanks Steve! I love the ADR gear, and thanks too for the Compex documents- my copy is a little dog-eared to say the least!

Great stuff.

If anyone needs the EQ section of the F769X-R I have it also, but it is printed on some wierd old blueprint paper that I think will not reproduce very well. I have to strain to read it as is.
