No, my family are careful around it and we no longer have a cat... I agree it would be very unfortunate if it ever broke. John :-#)# |

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. |

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. -- "I am a river to my people." Jeff-1.0 WA6FWi http:foxsmercantile.com |
