As to the vertical circuit: once you get it working at all, I have a suggestion
for it that resulted in "oohs" at the picture it made on my lowly Pilot TV-37,
which has the same circuit idea.
My change was to replace the capacitors feeding the vertical deflection
plates with much much higher value 6kV ceramic ones. Actually my
set could use 3 kV ones but yours need the 6kV ones.
I would suggest 0.05 uF but 0.03 would work. Parallel cheaper
ones if necessary. Its still not terribly expensive. What this does
is increase the time constant of the circuit so that there is no
"exponential droop" during the 1/60 sec. scan time. Then remove the
odd 20 meg resistor between the vertical oscillator plate and the
second vertical output plate.
The waveforms on the plates of the two output tubes will then be
much more linear than the very odd ones shown on Rider's (
and which were similar to those on my Pilot before the mod.) And due
to the much larger capacitors they will be essentially identical on
the picture tube deflection plates.
