Hi,
I am taking apart an old HV power supply made in the late '40s, probably
in Germany. From its size, the power transformer should be rated for
approximately 1 KW. It has an HV secondary winding 800-0-800 Volts and
two 12 V for filaments. It has a vacuum rectifier.
It has tuned chokes and I also found that a 10 uF cap is wired across
the primary winding of the power transformer.
So I guess that this must be a tuned-primary power trnsformer. I never
saw this before. How does this work? What are the properties of a
tuned-primary power transformer? Does it prevent current inrush at
power-on like a tuned choke?
Of course, I will replace the vacuum rectifier with solid-state diodes.
Should I leave the 10 uF cap acros ethe primary or remove it?
