Removing the Power Supply Unit

I was surprised to see the power supply doesn’t have a three prong plug! They must not have had a need for ground back in 1964. This will be the first thing I will add to my ToDo list.

Dust, electrical tape, no ground, no kidding!
On the schematic these are V4 5U4GB, and V2, V3 6BQ5
I’ve removed the tubes to safely remove the Power Supply Unit.
Illegible, Westinghouse 6BQ5 EL84, (?)X3 X8K, and Hammond 62-26 188-20

I de-soldered the colored wires to remove the unit.
