I bought one of Threeneurons (mike?) dekatron spinner kits to play with
some ideas. I'm new tubes in general. Anyway, the dekatron puts out
about a
50-60 volt "pulse" at NDX. I am trying to drop that closer to 5v but at
least less than 10v.
The circuit is high impedance, so you
may have reduced the pulse size enough to break it by loading it with
your resistor divider.
The output of that divider will need to go into a CMOS device so as to
not load down the divider.
if course old tube guys think of a "Cathode Follower" type of circuit
for something like this. Just about any small triode would be able to
pick off the signal and give a small voltage output. Lots of low price
COMPACTRONS out there.
