Re: [TCML] VTTC Plate Transformer

A popular, efficient, and weight-saving method is to use
just one MOT and use an AC doubler ( level shifter) circuit.

A single MOT with doubler and 833C tube can give 23" continuous sparks
without staccato.

Cameron Prince has used 2 MOT's in series (I think), then
doubled their outputs for a total of around 8000VAC.  This
can destroy the tubes if you're not careful.

For VTTC's plate voltage is very important.  I suggest using
at least 5kVAC on the plate.  Higher voltages can cause
destructive arc-overs inside the tube.  The plate lead choke
will help to protect the tube in the event of an arc-over.

Subject: [TCML] VTTC Plate Transformer



I've decided to build a VTTC.  I'm starting to gather the parts to build
it.  I have two microwave oven transformers from two different
manufacturers.  I tested them and they both have the same winding 
ratio, or
very nearly the same.  Would it be better to run these in parallel for 
more
current, or might I get better results running them in inverse parallel 
for
more voltage?  I'm going to be using an 833C tube.
