Re: [TCML] Resistive Control instead of Variac?

[Mddeming@xxxxxxx]

Hi,
 
It will work. However, where a Variac actually throttles back the power  
drawn from the wall, a resistive control dissipates the unused power as heat in  
the control. OK for small systems, not so good for bigger systems or in an  
enclosed area in the summertime.

Instead  of using a Variac with a NST, has anyone used a large resistive 
device to  control a Tesla?  I've got these very large theater lighting resistive  
packs.  They look very "evil scientist" with large control handles (kinda  
like a boat throttle.)  I've connected it to the Tesla once and it seemed  to 
work fine to control the power going to the NST.  Of course these  doesn't boost 
the voltage like a Variac, but I've thought that a small control  transformer 
could be used to buck-boost the voltage.

Any reasons why I  shouldn't do  this?
