And the interesting part will be to build the DC power supply for the many voltages
(-270V, -130V, -60V, +140V, +270V) and the heater supply.
A good source for information on how to do that would be an older edition of the ARRL
Amateur Radio Handbook. Those can be found, from used book dealers. I have a 1954
edition that would do well, though one from the 1960s is likely also good (perhaps better
since the earlier ones would have vacuum rectifiers, which in a newly built supplly
isn't optimal).
Chances are those voltages don't need to be tightly regulated, not like trying to
build a TWT supply... so the main thing is the transformer(s). Those too can still be
found, or can be built; Hammond (Peter Dahl) is still in that business.
The heater supply is typically just a suitably large 6.3 or 12.6 volt transformer.
