Aren't these for 120vac service? The preamp has an external
transformer with a secondary voltage of 18-20 vac. Would a filter be a
good thing at these voltages?

Yes it would still be a good thing, didn't look through all of corcom's to
see if they have lower voltage versions

Is there any reason a Corcom filter designed for 120vac wouldn't work on
lower voltages? Higher voltages would be a problem, but lower voltages
shouldn't. Unless I'm missing something about their design.

Peace,
