    Has anyone used balanced power with VTA kits? I’m just curious if it will cause issues since the power switch only kills one leg. If I’m understanding things correctly that would leave 60v. If I go that route it will be sequenced so the switches are kind of a non issue but it just got me thinking. Thanks.

    you'd be better off considering the various Furman models of line conditioners and/or line regulators, http://www.furmanpower.com

    It was really just a passing thought on how balanced power would work on a piece of gear that switches one leg for the power switch. I’m running a monster voltage stabilizer. Which is actually pretty awesome despite the Monster name. I just ordered a 1000 watt triad isolation transformer to put in front of that. I’m trying to deal with that last little bit of noise that is due to my power.

    It’s my understanding that when running balanced power there’s no longer a neutral. It’s 60v on both legs. That just made me wonder how these kits would behave when you tried the switch. Too many questions for me to go down that road but it is an interesting subject for me.

    yeah don't know how that would work, never looked at that......you may have to change the power switch on the amp to switch both hot and neutral....not just hot

    Why switch the neutral when there's nothing on it (or should not be; As PeterW has pointed out here, should be 0v on neutral and ground) . Dale

    Not when you’re using a balanced power isolation transformer. That’s the point of the post.

    In Europe we use 2 phase switches as we never know which side is neutral and which side
    is live. By the simple use of a dual switch we have eliminated all fuzz with polarity of outlets.
