I have noted a few TU members ordering 120 Ma transformers? Who sells these; aren' t they special order?
(I only care because I got into a petty argument with a Limey on Wiki over whether Neon Transformers were:"readily available at 120 mA". I argued, I and a friend at a Neon shop haven't seen so much as a 60 ma in 3 years, and most catalogs only supply up to 30 mA. The neon sign "rule" is not to blow a letter, or segment, requiring more than 60 ma. Most sign segments only need 30 mA. This limits expensive, special-order parts and risk of using a higher voltage than 15 kV, against underwriters.
The 120ma xfmr he quotes is a 240-VAC input switch-mode from England..most Neon is in the Americas, or Japan; 120 or 100 VAC. Such transformer would have to be special-ordered , and with extra shipping and a line transformer adapter--making it not "readily available" for the vast majority of the neon market.
Most signs are going LED, anyway, making big NST's even more of a rarity. I'm not surpised if I later learn many countries are banning Neon entirely on "ozone, rf pollution, hi-voltage and glass hazard" reasons or such rot. California is going to probably ban plastic bags, soon.
Sure, you can special-order 500, 1,000 mA if your Want---I'm sure Someone will wind you one. But, that makes it out of the realm of "readily available" and stock O.E.M, and Expensive...)
I really shouldn't worry about the Brits on Wiki--they constantly argue the "merits of the Vega", etc. Their articles are biased; like a GM executive wrote them.,. We all here in the US Know Vegas needed steel liners after 40k miles or so--they All did. To deny this is like saying the big pond makes you right; that we then have the right to argue about Aston Martin company and the Whitehall football team, etc. First hand experience precedes a laze on their duff simply "googling" things, but They don't. They call it all :"original research". I call it calling me a Liar...
Rant Over.
