Hello Frank:

Yes we did have better luck goin the single phase route. But do have
single and three phase avialable.

After making a new type of quad/yagi type of beam for 2 meters and
listening in on the ZOO channel 147.435 MHz and a few other Los Angles 2
meter repeaters I heard a conversation talking about a 10KW broadcast
transmitter that had some sort of shipping and or fire damage, but the
power supply was in good shape, down in San Pedro California. I called
the guy and will have the place and insurance point of contact Monaday.
But it does use 220 or 240 single phase, we will see.

If this was really for a 10 KW Transmitter tha used a pair of 3CX3000 or
a single 3CX6000 then this may be the ticket.

Hello All:

Looking for a good sized power transformer.

Needs a 220 or 440 3phase input, any where from 5200 to 5500 Volts out
at 4 to 5 amps. Will be using a input choke power supply so that will
keep the Plate Voltage at the manufacture spec's of around 5 grand on
the plates.



You might have better luck running single-phase, then all you would
need is a small pole-pig that you can get for a couple bills in just
about any well-stocked junkyard. Otherwise you will probably have to
roll your own, which can get quite expensive (iron, copper, oil, can,
vacuum pump, etc). So how much are you planning to spend on this
transformer?
