My 32S-1 manual says 800 vct and 275 volts center tapped with a tap at
115 volts. Which has to be wrong. Should be 800 volts each side of
center for the high voltage and 275 volts each side of center for the
low voltage. Which is about right for a choke input filter. The low
voltage winding has varied between transformer vendors with some getting
up towards 325 volts. But the transmitter is less skittish with 275 on
the PA screens.
