Hello all,

I am currently constructing a control unit for my 10kVA coil. I have 
always read that line filters should be used on both sides of the 
variac - to protect the variac from HV spikes and to dampen the surge 
currents they create. However, someone has told me that I should not 
use filters after the variac because high voltage surges can be created 
(similar to those created by rf chokes used between the tank circuit 
and the HV xformer). What do you think?


Cheers,
