Hello All,
I have a question about just exactly where in the power circuit I should insert a soft start switch. The "switch" is basically Tom McNally's idea about using an Amperite delay tube with a relay.
Mostly, people seem to switch the B+ before or after the filter stage. But in my case, I'm trying to switch a PS for two channels with only one relay contact something like this:
Why, you ask? Because I have a very nice 3PDT plug-in relay on hand (Rated at 15A/120VAC). One pole is needed to switch the Amperite heater off, one is used to activate the 12vdc relay coil, which leaves one pole to accomplish what I'm trying to do in the first place.
What do you think? My preference is to switch the PT CT, but who knows? Am I trying to blow myself up here?
Any comments appreciated, as always.
Chris
