Salvaged degaussing coil?

[Phil Nelson]

OK, I understand that my newly acquired CTC-11 (my first color set!) will need degaussing.

A few weeks ago, I salvaged various bits from a broken 1980s Sears color set that my wife had bought for $2 at a garage sale. Among those things was what looks like an automatic degaussing coil (2nd photo, where my son is holding the salvaged coil in front of my CTC-11).

I have a book that explains how, with a portable degausser, you would turn it on holding it next to the CRT, slowly move it away after a few seconds, then turn it perpendicular to the CRT before turning it off.

The coil measures around 4 ohms resistance.

Question: Can I just wire on an AC cord and stick it into my variac? And if so, what would be a reasonable voltage to use?

The book explains the theory of how some automatic degaussers work, but gives no clue to actual working voltages, values of thermistors & varistors, etc.
