U773 schematic needed - by Telefunken / AEG / Siemens ???

[rafafredd]

Hi there.

I have what looks like Telefunken / AEG / Siemens U773 (stereo?) limiter modules.

I've got some of these modules in a lot together with some other mixed stuff, and I really wanted to wire these up for good use, but I don't have any info like schematics or even pinouts/power requirements for those.

I've seen some for sale on Reverb.com, asked the seller if he could send me schematics, but never got a reply back.

Here it is on Reverb:

https://reverb.com/item/32048142-rar...-limiters-pair
Seems like it's all sold on that listing, so I thought maybe someone here was a buyer, and could provide me with the needed schematics and documents.

A picture of one of mine is attacked!

Please, I just need some readable pics of schematics and documents. You could take it with your phone, no need for fancy scanners and stuff. I just hate to see so many modules in such good shape sitting aside, with no use.

Help me!

Hi, I could not find anything about the U773. One idea would be to search for similar devices on Kubi's site, maybe that will help you.

For example from TAB the U373, or Siemens U273, Neumann 473 etc...any similarities? At least the pinout?

Thank you, but even the form factor is completely different in those.

The U773 are transformerless, with IC opamps, and the physical form factor is a lot thinner and smaller overall, so probably has completely different pinouts also.

Hey I got the v776 and two versions of EQ's from the same desk. There's schematics available for the v776 available and the w7xx eqs have the same pinout and power. If you can't locate them I have scans of them somewhere.

I have the schematics here somewhere, as well as a pile of those limiters. Let me do some digging. I can't remember the name/series that these unit came from. Give me a little time today whileI I am digging through stuff for "fall Cleaning"

We are having our morning coffee and talking about what channels we need to work on racking next... 10 channels of WSW C1 seems to be the answer.

Ok, after nearly finishing the second pot of Coffee I found you some treasures. You owe me a pot of Coffee. lol.

Desk: Telefunken/AEG VCM "Compact Modules for Sound Mixing Consoles"

Limiter U773 Details attached. Power is +/-15.

I hope this helps.

The last image is the list of modules available for the VCM series.

The complete desk has in and and output transformers in the same module format as the other modules.
I have some of these available, including the MS/XY modules.

I'm working on these right now, might consider the quad transformers if you're willing to ship them to Sweden Andre? They sound good without them.
It would be a dream to have a full console, never even seen a picture of one. Anything available in that catalog?

 

[andre tchmil]

Ok , I get back to you asap.

First module has 4x Haufe RK255 transformers.
the bottoms ones have 4x RK240 mic preamp things or 8X8 RK173. I have a lot of these.
Oh and I have the knobs and caps as well
