If I may be so bold, an instrument like this, being used for such an 
important purpose should be repaired and calibrated by the factory only.
We are talking about  instruments with a value of about 10,000 USD each, 
compared to that what is postage?

Thank you all for hints and advices.
Sadly it´s none of the supposed reasons so far.
Every time some secondes after beginning of stabilization I get:
"Error #4 GAIN Error System unsusable Consult Manual"
The Cs-137 cal source is still o.k. after 8 years
And so is the backup battery: Date/Clock is o.k.
But thanks Colin for the good idea of possibly aged high meg restors in the 
Maybe that´s it.
All I still need is a circuit diagram....
