Heard a couple hams on 2 meters this morning discussing a really good idea.
Thought I'd  pass it along on the internet.

One of the hams talking said he found that in OLD MICROWAVE OVEN's, was an
undiscovered
resource.  Namely the HV transformer that powers the Magnetron Tube.  He
has observed that
most of the transformers have a HV winding of +/- 2000 VAC (single winding)
@ usually
about 500 ma. capacity.  AND a 110 VAC primary.   This means that two
transformers matched of course, and placed in series, will provide 4000 VAC
centertapped, and 110vac/220vac primarys AT 1/2 an AMP, which is
more than enough to power that linear amp he wanted to build.  Also, old
worn out Microwaves can be had
for free or very cheaply at service dealers, and the local paper want ads.
FYI from a 'fellow junk collector'
