I haven't really seen too many detailed posts about this subject, but having a pair of Dynaco MK II's that run on the ragged edge with their output tubes even at 115V, I thought I would get opinions and experienced advice on the subject.
I have personally seen my wall voltage go as high as 131 volts, and as low as 118. So that being said, I have also noticed slight red plating at times while using the amps for an extended period. We all know that good output tubes are not cheap, and we all would like them to live a full service life.
I have everything needed to build bucking transformers for the amps to get their voltage down closer to 115V level, but before assembling them I did a recent purchase of a power stabilizer / cleaner that keeps the voltage at a stable 120V no matter what the wall voltage.
So in my mind, the stable 120 volts is much more desirable than doing the bucking transformers. The extra 5 volts being a constant, and not a huge amount, should allow me to bias the tubes to a level that keeps them from ever red plating from voltages going way high at the outlet.
Being a fairly new person to understanding electronics in depth, I would very much appreciate any educated, and experienced advice / opinions on the subject.
Thanks!
