Re: [TCML] Overdriving NSTs

Hey Phillip...

200%?? you put 240Vac into it? ouch you lucked out this time...probably wont be so lucky the next time around...good chance you stressed the insulation on the secondaries of the NST ...

Doubt very very seriously that the output voltage doubled. If someone had the ambition he could run a curve of output voltage AND LINE CURRENT! vs input line voltage up to the input voltage where the core saturated. Runs of a few seconds wouldn't overhead the primary windings enough to do damage. Results would be interesting. I would think the results would be just about universal, for NST's at least, because the guys build them for a price and won't waste any money on extra iron or turns.
