The lash up works. I can control a 120 VAC lamp with the dimmer
triggering the external triac. So at least it triggers on 120.

Before it goes into the range, I need some mounting washers for the
triac. These are bolted to a bare heatsink and I'd rather insulate
the triac than insulate the heatsink.

Still want to tinker a bit to see if the bare, out of the box, dimmer
can be made to work the triac with only the two wires they supply.

Wire it up on 240 powering a couple of 200-300W incandescent bulbs in
series, if that works then it should work fine with the burner.

The idea of getting a hardware store lamp dimmer and mating it to a
higher voltage higher power triac could have some commercial
implications. Especially if it can be done without additional
circuitry.

Most of the old stage lighting and centrifuge (industrial) stuff I've
seen. A: they want you to buy the carbon pile/rheostat or variac to
"fix it" and that costs hundreds or thousands of dollars. Or their
"updated" controller that only cost hundreds++.

I'm guessing but the one or two theater's left with rheostat controls
belong to Catholic schools or very old theaters.

Oh. Forget that stuff, I just want an option for my range.
