I was reviewing the missing pieces lists for some 5 amplifier projects here
and it looks like I'm only short one or two parts to complete each. This
happenstance must be a corollary of Murphy's law! :-)
If you happen to know Santa's email, please forward the following list:
Centralab 2500 series, type PISD (10 position progressive shorting) or UD (11
position) ceramic switch wafers. (1-5/8" x 1-7/8" diameter). Need 2 pieces.
Comet CV03C-1000 or CV03C-1400, 1000pF or 1400pF vacuum variable capacitors;
Several shaft options (trailing letter) are acceptable. Comet recently changed
the numbers on these but, I don't think that the new ones (with reallllly
confusing designations!) would be present yet on the secondary market.
Jennings CMV1-1000 with a 1/4" shaft also a possiblity. I can also make do
with their old spline drive version if the pricing is commensurate. Need 2
(guaranteed) working (good vacuum & alignment) parts.
Comet CV01C-250G-10KV, 250pF 10KV vacuum variable capacitor. Need one
(guaranteed) working (good vacuum & alignment) part
Comet MC1C-250 or 300pF, 15KV fixed vacuum capacitors. Need two (guaranteed)
working (good vacuum & alignment) parts.
Jennings Y1 (or CY-1), 1pF fixed, vacuum caps; prefer glass over ceramic,
they're cuter! Seeking three parts.
A 1000pF or greater, physically small air variable -- 2.5" hi max. including
plate travel. Prefer continuous rotation. A General Radio 1421-K would be
fine! :-)
73 & Happy Holidays!
