Re: Neon Sign Transformer
The beehive is called a high voltage bushing. The two 1/4 inch studs near
each other are the 120 VAC inputs. The 1/4 inch stud on the other end of
the case is your ground which must be connected to the green power line
ground. Test with a small climbing arc fashioned from two old cut up
clothes hangers. Set base at 1/4 inch spacing and top at 4 inch spacing ---
10 inches tall overall. Be careful --- this thing can kill you if you touch
it.
