W2INR of AMFONE.net fame has a 21E in his shack that takes up the whole rear
wall. He runs 450THs in it. Impressive sight and sound.

Hi, ALL
I was offered one FT-501 with the mains transformer
burned.
I got it rewound and today the set came back to life:
could hear some QSO's in 80m.
The TUNE just puts the IC to idle but speaking to the
mic gives no output.
The heaters are on and all the HV's are OK.
Is there some "easy" way
All this talk about big broadcast transmitters. A ham friend of mine in the
SF Bay area has a fully functioning Collins 21E and it's for sale. I have
seen it in operation. He has even made a remote control box to allow him to
operate it from his shack. It is pristine. Anyone seriously looki
Great interest here as I have the remains of several boxes from WNU commercial
shortwave station. Westinghouse MW-1 stuff.

There was an article in ER several years ago about running 3-phase
transformers on single phase, at reduced load. The recifier and filter
need to be redesigned, tho. A friend of mine is doing it successfully in
his homebrew KW amp.

Make a rotary convertor out of a big old 3 phase motor, a capacitor bank and a
few relays to control it. Figure 1 kw out per HP of motor size.
The really old multi cabinet rigs have enough empty space that one could redo
the internals into one cabinet and use the others as a cabin to live in.

One thing to keep in mind is that, generally, 1KW transmitters were 220V
single phase, whereas a lot (if not all) of the 5KW rigs want 220/440 3
