I have no local source for either an oilburner xfmr or a Neon xfmr.
I do have a couple of 250 - 0 - 250 transforemers salvaged from tube
radios. I have earlier used one of them and built a waltson cockraft
voltage multiplier to feed the Post deflection Anode of a homebrew
oscilloscope using 130C1P7 (long persistance phospor). stopping at about
the 4 kv mark.
Can I connect 2 of these xfmrs in series and build a waltson cockraft
multiplier upto 10 - 12 KV and build a Hipot tester? What are the pros
and cons. Searched the web but couldnt find any. Plan B is to use a
automobile sparkplug ignition coil (but dislike the high component count
involved).
This is to be used to test my hi voltage variable capacitor collection
(1 - 4 kv range), 1 russian vaccum variable Capacitor - 10 - 1100 pf- 5
kv and my stock of 813 tubes before using them to build an amp out of
them and a QRO largest possible sized magnetic loop for 160/80/40/30 m
