EDC 501J schematic needed

[George Pontis]

Hi Group,

I am in need of a schematic for the Electronic Development Corp 501J DC
voltage standard / calibrator (and too cheap to pay K-H a huge amount
for it).

Anyone have a copy or a pointer to one ?

Do you really need the high accuracy and precision, or can you get by
with a precision voltage reference IC with an initial accuracy of
0.02% and 1ppm/°C temperature coefficient?
