35amp transformer wanted

K

Karl Shoemaker

I build 10-11 volt power supplies for my repeater's transmitters. Since
they pull
around 20-25 amps I've been using 35 amp/12v rated transformers and
pulling
a few windings off to get 10 volts AC. The vender (Hosfelt) ran out of
these and I'd like to get at least one more. The part numbers and other
lables on the transformer are:
430-7001-4, EIA 6-9534, CLASS 180 H1 MEXICO. They are about 4 1/2" x
4", etc. Searcing on the web did not bring any current items to me. If
you
have any leads please email me [email protected] or visit my site

Thanks !!

Some people rewind microwave oven transformers for this sort of thing, you
don't need many secondary turns to get 10v out of one.

Dunno about the US, but in the UK having a bespoke mains transformer built
isn't *that* expensive. More than surplus stock though obviously.
