EMT 261 Schematics anybody???

I've had this emt comp/limiter laying here for 5 or 6 years and I'd really like to get it racked up(in fact I think the rack is done somewhere here in the building)

It works, But............I got lots of hum. I recapped it when I got it so I know it's not the caps. I'm thinking it's possibly a grounding issue or a jumper that has been left off. I had pin outs but nothing else to go on.

Anybody got schematics for this so I can figure out what's wrong. It seems
like it might be a pretty cool compressor.

Looks like I have solved the problem without schematics.

The hum was due to the proximity of the 24v power supply to the EMT unit. I'm going to run an external 24 supply and probably put my lone Telefunken U373 in the rack with the EMT so it won't be lonely.

Schematics would be cool though if anyone has them.

Great , thanks so much :thumb:

That schematic link does't work anymore. Does anyone have it?

It is now in the Technical Documents section.
