Hans,
I have yet to see a manual anywhere for these references, but they
consist of the "cal" generator (0dBm) from the 435A power meter, and a
10544A OCXO for the frequency reference.
in my -K26 units, the 15 pin (double sided) pcb connector takes a 10544A
OCXO.
it's possible that EFC (via a trimmer pot) is added in your variant. can
you install a 10544A?
is the power/return wiring correct? that may allow you to figure out
the rest.
regards,
walter

Just got my hands on an old HP 435A-K06 Power / Frequency Reference
But the internal frequency oscillator is missing
There is a 15 pin plug as the one used for 10544 / 10811 but the wiring is
different
(found out that output is rewired with a filter through a NC pin)
Searched everywhere, but I cant find any information about 435A-K06
Did see a mail here mentioning 436B-K26 (Walter Shawlee 2)
Any one with info that can help me get this running again?
