Follow on post updating results; closing in on 6 months now since I built and started using a bucker transformer with my M125's. Have experienced zero issues with either M125 during this time frame. My first few months of M125 ownership the path was littered with blown rectifier and power tubes, also witnessed multiple red plate events. Little did I appreciate how much house voltage commonly varies. I checked it once and it was 120 so I figured I’m good. Wrong! In my case actually varies anywhere from 118 to as high as almost 123. The latter is where all the fun (not!) would begin.
The bucker drops my incoming @3.5 volts. Now I turn the amps on without worry anymore. They just sit there glowing calmly. No more buying fuses in bulk! No more nervously eyeing the amps every few minutes for evidence of the onset of a red plate. No more dead amp syndrome. Not it's just kick back and enjoy.
