Using the Fluke 732A as voltage reference improved HP5065A stability,
but not very much, so I looked closer at the constant-current
generator and the C-field pots "calibration":
... and found out that the current-sensing resistors R10||R11 have
a very high temp-co.

Never attribute to malice what can adequately be explained by incompetence.
