RE: [TCML] NST modification

["Lau, Gary" <Gary.Lau@xxxxxx>]

I really doubt that the output is DC, as that would be unsuitable for neon signs, as well as Tesla coils.  If it is in fact a high frequency (AC) inverter sign transformer, maybe the output is AC-coupled through a capacitor, and that's why it reads open?  I'm not sure as I've not played with such transformers.  But it's clear that it won't work for a TC.  The non-standard 13kV rating also makes me suspect that you have an inverter.

The tank circuit is unaffected by the power supply.  The power supply simply has to be a conventional 50/60 Hz core and coil transformer.

Subject: [TCML] NST modification

Hey all,
I'm in the process of building my first TC.  I finished all my
calculations and was about to begin actual construction of the tank circuit
and coils, then it hit me;  my NST (13KV, .3A) may have a DC output.  I
checked resistance across the output leads, and sure enough the meter
read infinite.  This leads me to conclude that my NST has a rectifier inside
the case.
My question is:  would it be easier/simpler to design another tank
circuit OR  is it possible to just open the NST case and remove/bypass the
rectifier?
If i missed anything obvious please let me know.

Many thanks,
daniel
