Yes.
I've had no problem with turning the rear switch on. I've tried it with two 1000s and one 1500. There are no clicks, pops, farts or burps. On the 1500, when you turn it on, you will hear the pleasant sound of magnetostriction in the 30 pound toroid that graces the innards.
I have noticed when the rear switch is turned off on the 1500, and the front switch is still on, for about 753 msec, I hear a high frequency squeal in my VP160 as if someone quickly choked a squirrel. It surprises me every time, and every time I have to remind myself I don't house any humans or squirrels in my 160.
