RCA Victor 8PT Selenium to Si Conversion

RCA Victor 8PT Selenium to Si Conversion

I would like to convert this TV's 64 year old Selenium to Silicon.



It seems to differ from most Seleniums that I've seen, in that the AC from the transformer comes into the center, and branches out in 2 directions. On one side, wire 1 - returning to the transformer secondary, going through the 60uF and wire 2 going feeding the B+. On the other side of the Selenium, passes through another rectifier section to ground.



In order to convert to Silicon rectification, will I need 2 Si diodes: 1 going from the AC to the 2 yellow wires, and the other from AC to ground?

Note, I am aware that I may need to add a dropping resistor.
