First you have to use the right caps for the 22-5001 or they will
short. See old threads for subs.
Hum then quick breaker pop is almost always the caps, damper,
hoz out or shorted oil cap. Longer pop ( apx 10-15 sec ) the
tripler.
Quick checks are unsolder one end of oil cap. If the cap opens
the pix will pulsate but work.
For H out just hang an ohm meter on the H. out collector to GND.
Should be in the megs. If shorted unscrew the H. out ( 121-831 ).
Then the damper ( 103-193 ) then caps etc...... Dont run with any
hoz parts unloaded. Oil cap you can run without a short time.
Last hint for now is all the original boards have plug in semis. The
sockets will get intermitant especially the IC sockets on the 9-86
color board.
