Beautiful restoration job. So far so good.

So far as the power supply, doesn't look that hard to make. It would be nice to know the original power transformer and choke specs, but at least you know you need 411 volts or so at the rectifier under load (which you can estimate), a 5 volt 3 amp winding for the rectifier, and you can add up the 6.3 requirement for the rest of the set to get the spec for that winding. You can pretty much always use transformers with higher current ratings than you need, but never use an underrated one. You have plenty of real estate in that cabinet, so size is not important.

You can also use slightly less inductance chokes and slightly larger value filter capacitors. Back in the day, filter capacitors were very expensive. Now chokes are expensive and capcitors are dirt cheap.

Do check out the field coil and output transformer windings though, to see if there are further complilcations to consider.

Download this free calculator if you want to roll your own supply. It's excellent, I've used it for many projects. Once you determine what you need you can post a WTB in the clasifieds on this forum. For that matter you can post a WTB for the whole power supply, somebody might have a spare.
