[earlytv]

In 36 when your TV was up and running, over here we had some kits
and some HAM radio opps played with TV. I am trying to build one of those
KITS but find only the 878 HV tube for 7000v anode supply for CRT.
The 878 in a large chunk of glass. Did you have other tubes for a line
HV supply with about 7000v out and 15000 peak inverse?
I found tubes such as 1B3 were not meant to have 50 or 60 cycle power, they
were meant for flyback use only?

Thanks

Dennis
