Anyone using one of these with their vintage amps? In my current location, the wall voltage is 120-121, but at my other place it's more like 124-125. I just got one and, so far, have only used it with a couple of cathode biased amps. No discernible change in sound or feel, which is good, but now I have peace-of-mind that the amps' transformers, power sections and filaments aren't being stressed from over-voltage. I will have to check the bias of my fixed bias amps with the dropped voltage, but that's for another day(s).
