I have new neon sign with a bad transformer (has a short and works sporadically), it is a 5kv 15MA transformer. I bought a new one that is 5kv 30ma and the neon fades towards the end of the run. It is nice and bright the whole run with the original transformer so I am assuming the 30ma vs 15ma is a problem.

Any advice, im having a hard time finding a 5kv 15ma replacement.

Well you\'re overloading the neon tube and may cause damage to it.

I found some 4kV 15ma electronic power supplies online. Might work fine.

As a test, you could put a 330K resistor in series with the neon tube.
That will limit the current to 15 mA.

However, the power rating needs to be in excess of 75 watts.

As well as the constant high voltage.

Nice. Did you ever consider building a lexan box to mount it in?


No, my family are careful around it and we no longer have a cat...

Did it rub against the transformer?

The photo doesn\'t show the chrome metal box that the transformer is
mounted in. The HV outputs are in two chrome metal tubes that the tree
plugs into...
