Well, recently Varian has come under fire for what I'd call "unorthodox" HR
practices. The defendants lost their case against Varian last week.
Alex, you might take note -- one of the issues in the case involved online
harassment, and while the echoes of the case will continue for years, it
sets a chilling precedent for any of us to criticize others online,
regardless of reason or justification.
Obligatory amp content: ham radio featured an article about monoband amps
that used the chassis for the ground side of the tune and load caps in a pi
network, and a plate of aluminum or PCB insulated from the chassis unisn
teflon sheet as the "hot" side.
Combining this idea with the old ARRL projects of monoband rack-mount RF
decks, consider how small you could build a set of monoband amps with the
sheet capacitor, made to be slightly adjustable, in parallel with an
appropriately sized fixed capacitor.
Rich, your call -- would it be reasonable to bypass the plate supply at a
chassis wall, and hang the plate choke externally? I might have to draw a
picture of the silly arrangement I'm thinking of...with 4CX250s and their
cousins still plentiful and cheap, this might be a fun project to write up
for charity -- I mean, QST.
I think I could fit 5 bands in a single 6U 19" rack. Anybody got a 5-pole
air relay? ;)
