[Test-Equipment] Late model HP-410C info needed.

[John D. Farr]

Hello, and thanks for reading this. I have a late model HP-410C but both the
HP manual and the military manual only cover the early models. The
difference is that in this model, the circuit board containing the chopper
circuits has been replaced with a very sparsly populated board containg two
IC's (one might be a dual transistor) a few resistors, capacitors and
trimmers. Does anybody have a schematic of this board? I would certainly
appreciate a copy or at least the description of the adjustments that are on
this board. Some of them are un-marked. I would be glad to pay postage and
copying expenses.
thanks, John.
