Forgot the technical name. All the trannys have to be in "phase". These I believe Triad
trannys. They could be Stancors. The Allied catalogs listed several manufacturers.
They could be Hammils?
The way I did it. The color code of the input line voltage was clear. What goes to neutral
and the Hot side. Ah. The extra heater winding will be used to power up some
green LEDS, 12v fans, new regulated negative grid bias board and the soft Start.
Yup. Those RED wires. 680vac 340-0-340. Interestingly. This 12 tuber is only using one
of the HV center taps. the others go to parking posts. The ten tubers. These center taps
are attached to the chassis thru a resistor.
Alright. Turn the box on. One lead of the VOM is attached to incoming AC line in Hot.
"black wire". the other lead. To one of the HV red wires attached to the Bridge rectifier
array. Make note of the voltage reading. Then the other Transformer leads to be phased
with the others. The voltage reading. you will see a high side. & a low side. High to high.
Low to low at the bridge rectifier tie posts. This method works with step down or step
up trannys.
My apologies. I don't know how I uploaded repetative photos.
