Here`s the info, guys. I have both the op-amp, and photochopper version
manuals, so
if you want more info, it`s there. My 410C
uses the photochopper, but it works well, so I haven`t modified that part of
it. I put a 3 terminal regulator for the 6.0/6.3 Volt EA53
heater. This reduced the "zero drift" quite a bit.
Cheers all!.........................................Don C.
