[TechAssist] Re: Zenith TV 9-1474 Isolate Transformer

Hi Tony,
cut the foil for the filament leads to the Crt socket, tape two wraps around
the core of the IHVT and solder to the socket of the crt.
also remove any caps in those lines.
You should also explain to the custormer what you have done so they know.
This is the OLD fashioned way of developing the filament voltage for the old
crt/s
also you can add another wrap if you need boost.
Good Luck
