Re: [TCML] Variac Question

Another problem is that the core has no gap.  You need a gap to prevent the core from saturating.  Maybe you could make a gap with a slow bandsaw, as long as the whole thing doesn't go  SPROIIIIINNNNNG!

I don't think so.  Considering that the neutral line is common to input and
output, there is no attenuation of anything on the neutral line.  You may
wish to review the web page I wrote about how to hook up EMI filters:

Hello everyone,
I was on this list about 20 years ago (wow does time fly)! I'm doing a big
rebuild and getting my coil back together now. My question is about using a
variac as a line filter? Will that iron core attenuate RFI better than a
commercial line filter?
