Hello,

Does anybody know of a suitable replacement for the optical rotary
encoders that were used on older Agilent/HP 65XX and 66XX power supplies?
These were phased out on the newer generation supplies which use
mechanical types. Agilent no longer has any stock, and advises me to
replace the entire front panel PCB at a cost of $631.00.

I believe that the encoders are part #0960-0822. I have no documentation
on them. Pictures can be seen he

Thanks.


'scuse my ignorance but where are rotary encoders used in power supplies ?
dialling up voltages ? so can replace with something else only functionally
the same ?
