Subject: Sale: New neon transformers
All,
I made a bulk purchase of new Jefferson/Magnetek neon
transformers and I am making these available to TC builders at a
fraction of the usual new price. Shipping (from NJ) is additional.
They range in output voltage from 5kV to 15kV. They have 277volt
primaries so a step-up variac or step-up transformer is required to
run them from 120V or 240V. As a test, I installed a 12kV,30ma,
277V primary neon tranny, along with a step-up transformer, onto
my 42" spark Tesla coil, and the spark length decreased by 2"
compared, with normal operation using a 12kV,30ma, 120V input
tranny. This seems to me like a minimal loss going through the
extra step-up transformer. In this test I applied the same voltage
(around 120V) that I usually apply to the 12kV,30ma, 120V input
tranny. When used in a TC giving shorter sparks of let's say 18",
the decrease in spark length would be less, perhaps 1".
I am also selling (4) of these new step-up transformers (which are
actually step-down trannies), but can be wired in reverse for step-up
results. These transformers accept a 120V or 240V input, and
provide a 254, 266, or 277V output, and are rated at .75kVA
(GE brand). Input and output connections are wire leads, wiring
diagram is included.
Neon trannies available, 277V primaries:
QTY kV mA PRICE $ (ea)
1 15 30 32
1 12 30 27
2 7.5 30 22
1 7.5 60 30
4 5 30 20 (secondary insulated, not
midpoint
ground)
4 step-up transformers 12

1 6 60 35
The neon transformers are of the standard style with an insulator
at both ends.
If interested, please e-mail me directly at < FutureT-at-aol-dot-com >
and include your state and zip code if you'd like me to calculate
shipping costs.
Thank you,
