Sprague 2X.1-1000 filter capacitors and 854-B power control assembly

[Tom Hunter]

Thanks Matt.

The actual equivalent filtering can easily be achieved by two small Y-class
AC caps, but the 8 male spade connectors on the original Sprague cap are
also used as a wiring hub. My problem is more of a cosmetic and
reversibility nature. I am trying to find something which doesn't require
drilling new holes into the power control assembly and doesn't look
horrible when you open the rear door of the Lab-8/e.

Chuck's suggestion of gutting the old Sprague capacitor would be ideal
except for the PCB toxicity issue (maybe I am just too paranoid with PCBs).
The "bathtub" can is soldered and partially crimped together. Heating the
solder joint would get the mineral oil with the PCB in it very hot so I
would expect toxic fumes once the can opens. The next problem would be what
to do with the oil after I successfully opened it and how to clean
everything so that no toxic residue is left.

Best regards
Tom Hunter
