TAB U273a ?!?

[tonfisch]

Hello all
I have some of those units, they need some rework....
Has someone the schematics for this Compressor / Limiters?
They were produced by Tab for Siemens.
They have unlike the U373x ore U273b ( Siemens ) dircrete Opamps ( NTP M100C ) in there.
The forntplate looks identical to the U273b made by Siemens, with the little metering.

I allready searched kubi´s / silentarts / etc.sites ( btw. manny thanks fore your work.)

Basic Pinout is clear to me but the Stereocoupling-thing...

Manny thanks in advance

I have acquired the same pair of TAB U273a compressors and would love to get the correct
schematic and any additional info about them.

Is there anybody here with these resources or can point to a similar schematic f.e. U273b?

Thanks!

Thanks a lot Jakob!

But is this Siemens U273-A identical to the one from TAB, that I am referring to?

I don't se any NTP opamps in these schematics, so I guess not :-(

That’s what I thought! The hunt for the schematic goes on, who can help?
