Re: Looking for mini-VFD for 120VAC/1ph

Hi Doug,
The built in control is ( in my guess )an inductive load capable
diac + triac dimmer type control. You'll probably have to take the
trimmer apart, bypass the control. Usually this is a simple as a
2 wire join: to bypass the "dimmer", then your $30 unit should work.

I think its failing to work so far due to having 2 "dimmers" in
series ( with the $30 speed control running the router speed
control ), so neither can get proper triggering off of the AC zero
crossings.
