Re: 120Vac on a 115Vac transformer

I used an isolation transformer (used off ebay) that had an adjustment switch 105, 115, 125 for the input voltage. That way I just set it to 125 and I get about 110 to 115 at the output(when loaded). The voltage does creep up a few volts under no load. I think it is either 250VA or 500VA. I was getting some ground noise due to my setup. But I may try it out again when I get finish recapping my Mark 3 amps since the B+ is over 500 volts when my AC in is 124V.

I like the buck idea though!
