When I first saw this tv set (what that chassis?, look interesting)
and successfully fixed that without schematics at shop. Being a HV
regulation distortion (wider when brighter) pet preeve guy. I was very
impressed with this thing (no distortions!) even displayed grid
PERFECTLY without vertical lines squiggles just under each horizontal
lines.
This made me all the itching to study schematic that Hitachi designed
made this wonderful set so nice. Especially this one pin, outside the
circle of pins, for the screen/focus network on the flyback that is
normally grounded was not, it is made part of other circuit is what
made me really interested.
One of few sets that can do this well is their RCA 13" series due to
direct control of HOT base drive and many in projectors with active HV
feedback regulation.
Thanks & cheers,
