Just curious - what are the costs of these (Neonix) units? I have an old beer
sign with a bad transformer, and I was thinking of using a solid-state unit.
I have been quoted around $100.00 for a solid state unit (brand unknown)
from a local sign shop. I can get a used conventional step-up unit for
around $25.00. The use of the sign would be very minimal, and I would
like the weight savings of a solid-state transformer, but I cannot justify
the extra cost.
Also, the original transformer was a 9000 unit. Does it hurt the tube to
use a 7500? Or a 12000? What type of ammeter do I use to test the
secondary current (I was told to use 24 ma. as a current goal)?
