[Milsurplus] Fwd: FS: mother of all isolation transformers for boatanchors

Sat, 02 Aug 2003 23:02:25 -0400

Yep, I have one of those, Darn thing is a monster. Had it sitting under
my
work bench for running the larger boat anchor rigs, like the BC-610 and
T-368 during refurb and testing. Works great, only thing I complained
about
(I got it for free) was A) carrying it downstairs, and B) it weighs so
much
it put a permanent bow in the 3/4 inch plywood bottom shelf on my bench.

But for setting a high current 115 or 220 VAC rig up they can't be beat.

I eventually built a roll around carrier for it out of doubled up 2X4s
that helped quite a bit as I can take it to the equipment under test,
and
NOT drape large AC cables across the floor.

Get one if you can, but take help to move it, and a pair of 2X4s aids in
the
moving / lifting process.
