Check this out..... plus it's an interesting site worth
bookmarking.



Then, after u have added it to ur shopping buggy.... all u gotta do
is get ur local power co to upgrade the pole pig + drop wires in
front of ur home!

A real steal... compared to that $8750.00 Alpha.

I'd suggest using the 7073 vac tap... which will give you 10 kv
dc under load. This is the perfect xfmr ...for a pair of 3CX-
20,000A/C7's. Also suitable for a pair of 4CX-15/20 K's. All those
tubes are rated at 10 kv @ 6 A. Now I'd highly recomend a Buss 10-
kv HV sand-filled fuse [10" long] Dunno about a "glitch
R"...perhaps a paralleled pair of those 50 ohm 1 kw globars [2"diam
x 24" long]

That transformers construction looks familiar. Several of us used a
transformer manufacturer just outside of LA which was called Woodys
transformer at the time. They wound about all the transformers for
the 11 meter amps made in California and surroundng states. Woody
retired and his son now runs the company. I think it's now called
"WTS" which is short for Woodys Transformer Service. They had some of
the best prices available for HV transformers. They were so cheap
that I could pay the shipping to Ohio and still come out ahead. That
was buying like 10-20 transformers at a time. There single lot price
is almost as cheap. I don't have a website for them though.

Some of the other builders down south (amplifier alley) who are still
in business use Galaxy Transformer in New Jersey. They make some
special transformers to be used with an alternator less the
rectifiers/voltage reg. making it a 3 phase generator. The primary
then is about 14 Vac, 3 phase. The secondaries can be any voltage
needed. That's an easy way to run a big tube mobile.

Their website is;



Best,

Try this again since it claimed to post it then didn't.

That transformer looks somewhat familiar. There's a company just
outside of LA named WTS which is short for Woodys Transformer Service
that wound transformers for most 11 meter tube amps made in
California and the surrounding states. I bought them also since the
cost was low enough that after paying higher shipping, I still came
out. I don't have a URL for them.

Most down south (amplifier alley) building amps use Galaxy
Transformer in New Jersy. They make a custom transformer to work with
an alternator that has the rectifiers removed making it an AC 3 phase
generator. In other words it has a 14 Vac 3 phase primary. That was
an old way to run tube mobile amps.

Their URL is;

I often order HV transformer from a local shop. price: RMB2 per VA(25C/VA),
a 1000VA CCS HV xfmer =$253(TYPE R or C iron core), if it is "EI" type iron core,
the price is $150.
