What's strange about it? It sounds like a typical RF Harris commercial HF transmitter. The Coast Guard uses a bunch of them, as do the commercial short wave broadcasters.

Oh.  It just clicked.  The original author meant "the bird religion CB watts".   ;D

Well,its not being sold to the coast guard unless a guy named Wizard has them as a customer.

Where did I say it was, please? I just commented on what it likely was. Geez, we got some touchy people on this thread. Sorry I bothered.

50 amps at 240 volts is 12kW - with unity PF. So 15kW out means he really has something there!

I'd like to see the original listing.  The posting here makes no sense at all to me.

The 3CX*****A7 family of tubes (3CX10,000A7, 3CX15,000A7, and 3CX20,000A7) are air cooled triodes that can be run in the grounded grid cathode driven  configuration, similar to the more common 3CX1500A7 (8877) used in certain Alpha and Ameritron amps for example.  

Assuming it is run in a properly constructed amp, a 3CX15,000A7 will deliver around 20-25KW out with 1500 watts drive.

I am not advocating this, but there are HAMs (not just CBer's) who run this much power.

But getting that much power out of the mains on single phase is not easy....

Unless it is three phase power. I would be surprised if it was not.

240 volt three phase isn't that common.

If it was a commercial radio transmitter it would be. Most of those sites bring in three phase power.

Just don't mistakingly use that stinger leg for a 120V piece of equipment. POOF...

240 volt three phase isn't that common.

At my shop (where my main HAM shack is located) I have a 240 volt 200 amp single phase service.  From the P=EI formula 240V X 200A = 48,000 Watts.  That means I COULD run a 48,000 watt amp on my single phase service.  Granted 3 phase would be a better option, but it can be done on a single phase service.  In fact the local power company will supply up to a 400 amp (96,000 watt) residential service if needed.

Over here, single phase is not usually more than 100 amps at 220. Something that size would be run off three phase 415 volts. The HV PSU is easier on 3 phase, too.

How do they handle regulation on a 400 amp single phase supply? How close do they have the transformer?
