Hey Phillip...starting at 0 volts and bringing it up to operating voltage (120vac) is fine as long as the NST has a load attached to it. As far as going into the 125+ range with no load attached can be a bit hard on the insulation. NST's are designed to put out the nameplate voltage for brief periods of time when the neon tube is starting up ( not yet running) but once the tube strikes and lights up, the resistance is pretty low anyway ( something about negative resistance in a plasma). Kinda makes you wonder about all those NST's trying to fire off broken neon lites and how long they last in that situation...

With all this talk about how weak the insulation is on NSTs I just assumed it was a bad idea. Is it okay as long as the NST isn't running open?
