The leakage inductance would be enough to make some very high voltage
spikes when the triac opens. I suspect that the leakage inductance
of a transformer of the size needed for an 833 filament would be
quite substantial as far as the triac is concerned. Any light dimmer
that I have ever seen states FOR INCANDESCENT LOADS ONLY.
Give it a try with a small transformer and resistive load with a
scope looking that the AC

Whats inductive about a filament load??? The filament transformer
should have low leakage inductance as well, yes??
