Left Rack иии
233D Transmitter Restoration Project

 
The Left Rack contains the High Voltage Power Supply using six 872A diodes.

The 233D runs off of 208 VAC 3-phase 60 hertz.
This being one of hurdles an amateur radio operator would have to solve. It's not impossible however. 220 volt single-phase to 208 volt three-phase rotary converters are readily available.
A new 3-phase service for your house, even if your neighborhood is wired accordingly, would be pretty pricy!
