[TechAssist] Re: PTK 169PTC P60153EB reg. B+ too high shutsdown

Al, yes I have the manual and I`ve worked on a zillion of these, that`s why I`m
pulling my hair
out and I don`t have that much to begin with. Tried a known good flyback, no
change, all raw
B+ voltages and standby voltages are there, but set will not start, comes up 3
times and then
just sits there, have seen the standby voltages too high but not run voltage too
high, at 69 volts
on a variac the collector of the hot has 134 volts on it, at 70v on the variac
the set shuts down.
I`ll get back to the pain in the a** on Monday, have a good weekend Larry E
