Re: Triac-dimmers in TC's
I made a little box that takes in 120v from the wall, and then leads
it out to a bunch of terminals. I made it so that playing around with
my NST's would be easyer. But I had a dimmer on their for one of the
terminals, and it is all screwed up now, just from use. It has only
been about a month too. Just my thoughts.
