A. R. Ref3 and Aesthetix Atlas 12v trigger ????

I use the triggers to turn on my Moon amps and a cooling fan for the equipmet.

BTW I installed trigger wire and glad I did, its a nice bonus to say the least.

I have used 3 different ARC preamps with 12 volt triggers with several different amps, including SS and tube and never had any problems. The startup surges for preamps are in general far lower than for amps, and some amps incorporate soft start features which reduce surge. In addition, you have breakers on the circuits should there be any overload. These triggers are designed specifically for this use and I would not be concerned.

Both my ARC LS25 mk2 and Ref 110 have the 12v triggers. I thought about using it but changed my mind. I am not sure that having the preamp and amp (tube amp) turn on at the same time is a good idea. I think it is better to turn them on one at a time and create less of a power surge.
