Re: New coiler, also in search of 15kv and De-Potting tar filled NST's
Original poster: Ed Phillips <evp@xxxxxxxxxxx>
Hi Drake,
If you don't have any luck searching your local neon shops, I can
offer you a 60 ma transformer for between $50-$75. France and
Allanson's that are mint get the most$, Newer Magnetek's are slightly
less, and if the bushings have a chip (a cosmetic issue rather than
performance ailment) then I adjust the price downaward accordingly.
Seeings that there has been a lot of talk with regards to dislodiging
cores and coils from their tar filled homes, I thought I'd mention
this; I have half a dozen or more 60 MA 12 and 15 kv NST's that have
had one or more of the HV bushings sheared off. These are other wise
great units, SO, if some ambitious soul wants to have a backyard tar
melting festival, these would be PRIME candidates for either
de-shunting and/or just paralell connection of multiples for greater current...
If interested in one or more, let me know. I also get great
commercial shipping rates and am very flexible with regards to
crating and shipping...

I've had good luck repairing transformers with "sheared off
bushings" by just melting away the tar around the bushing until I
could get access to the HV lead and and using a new bushing made of plastic.
I found a bunch of transformers lying in the ice plant beside a
freeway on ramp once. Apparently they had slid off the bed of a
truck when the guy went around the corner too fast. Saw one sticking
out onto the curbing and returned and found a half dozen others, most
of which had the bushing beaten up at one end but with enough of the
bolt left that I could easily get at the HV lead for a new
attachment. One was in worse shape but I was able to melt the tar
away from the opening in the case using a potent hot air gun. Made
new insulators from fiberglass rod because I happened to have a
bunch, but I think almost any insulating material (including dry and
wax-impregnated wood) would work just as bell.
