I believe he meant a variable autotransformer (Variac) to vary the voltage
to the lights. I worked at a station that used them. Expensive, yes. But
they do not generate any noise like SCR/Triac dimmers do. An isolation
transformer will not eliminate the noise.

>>Use A power (autotransformer) no noise, no filter required
