Hi Bill,

So I will try to replace IC201 (ICL7650) as stated in the Service Manual.
But, if it so I fear that the calibration will be lost.

At least 48 hours.

It's a Transvolt 9154C actually (4 cells with t° stabilized at 0.01°C) but, 
I
don't wish to calibrate it because it's still under calibration.

Thanks.
