Re: [TCML] ferrite variac

[bunnykiller <bunnikillr@xxxxxxx>]

if you are planning on using 120VAC to power the homemade variac.... I 
would go for something other than ferrite...  besides, a 4"dia X 4" tall 
variac would handle about 5-9 amps ... I would start at a 20A rating for 
tesla coil usage..

I am planning on stacking them together for one big ferrite core.  do you guys think that this will work for a variac core?  or do I need a laminated iron core?
