Here the complex chain drive is finalized. Spur gears used on the inside of
the inner front panel.
The idea of the 3 x chains is to get the tune + load turns counters, and
the bandswitch knob located in the correct positions on the outer panel.
After some preliminary attempts, this latest version works good...and the
front panel simply slides off....leaving all 3 x chains intact.
On a side note, I shipped the new 397 uh plate choke today, along with a
pair of .01uf @ 30 kv disc caps, used for bypassing at the cold end of the
plate choke....used for the lower bands. A pair of 500 pf doorknobs will
also be used at cold end of the same plate choke...for bypassing at the
upper bands. A pair of 100 amp supercon panel jacks also shipped. It's
slowly coming together. This chain drive setup complicates things quite a
bit, and required a lot of head scratching. But it's finally done...and
works. The mapping has yet to be done (turns counter markings vs actual pf)
for the tune + load caps. Once done, the mapping....aka .....'cheat sheets'
can be made up.
