Allignament Procedure for ADR F760X-RS

[AUDIOPOTS]

Hello guys, greetings! Frank Santa, I have an ADR unit F760x I just do a re-cap of all electrolyte, the unit works fine except channel 1 was not delivering the same levels as channel 2, I'm looking for information on performing internal alignment would need the manual and what is the procedure, I have: function generator, true rms AC millivoltmeter, Oscilloscope, etc, but I'm not familiar  with this type of operations.
The ADR is factory with balanced inputs and outputs via ELMUS type transformers 82 and 83, I have understood that to apply a sinusoidal signal 1Kz for example, would have to bridge pins 1 and 3 of the input? and for the same output?, also I have doubts that any resistance would have to use the output shunt?.
Appreciate it if anyone has expereriencia in all this can help me, I'm truly at a crossroads.
thanks
Frank.

Hi

Just joined.
Looking for Calibration notes for the F760X-RS as well.
Tried to Email you Bernd, but as a newbie I'm not able to. :-(

Any help would be most appreciated

Great. Thank you for the link.
I've do some comparisons of the circuitry, and see what's different. Hopefully not much

Hallo Bernd,
ich bin ebenfalls in Deutschland und Besitzter eines ADR F760X-N . Er müsste mal fachgerecht durchcalibriert werden. Wie Sie sagen, haben Sie die richtigen Unterlagen dafür , Wäre ganz prima wenn Sie mir einen Link schicken könnten. Falls Sie ein Experte auf diesem Gebiet sind und auch Reparaturen durchführen , könnten wir uns auch darüber austauschen . Vielen Dank für jegliche Hilfe. Ich bin in Berlin ansässig.
Viele Grüsse
Thomas
