Hi All,

I recently came across a very large sum of neon transformers. The
input is 277v for the primary, the secondary is kicking out 30
miliamps at 7500v. I have some pictures of the transformer on my
website: www.doranaerospace.com/Images/neon

does anybody have any idea of what they are worth?

Thank you,
Bob Doran

Their worth is determined by the market. Newer neon signs use high
frequency inverters to power the tubes. They are somewhat safer, cost
less, weigh less, good power factor and more efficient.

Neon is being supplanted by high frequency luminescence "wire/tubes"
and LEDs. What you have may be museum pieces before long.

They'd be worth money to Tesla coil addicts. If they are identical
they can be paralleled for more current. The 277 volt input would not
be desirable for TC use though.

I paid $40 for a new oil furnace ignition transformer (about 75 watts
more than what you have) for my first Tesla coil. Then a year later
spent $20 on a new NST that was about twice the power. Later I wound
my own transformer from scratch and spent about $100 on magnet wire.
