Hello all,
So there are UK coilers,
I looked in yellow pages at sign manufacturers. Found those that
specified
neon signs and made a few phone calls. In the end a very helpfull lady
supplied me with a 10KV 50ma from a company in Bristol. Infact it cost
me
nothing as my son was interested in the subject for a school project and
she took sympathy. By the way a new one would cost about £80.00.
