Hello John, I personally think your AC transformer is right in the ballpark "perfect AC voltages" to your rectifier tube in the high-voltage ratings you described in your previous posts since your checking voltages with tubes removed. Seems you are getting 393 volts to pin #2, and 393 volts to pin #3 plate connections which equal 786 volts reading directly across both pins. Separate readings from each pin#3 #4 to chassis ground should read 393 volts each to chassis ground thru your volt meter.Sounds about correct voltages to me since your all your tubes are out of chassis during your tests. Just trying to clarify my previous post. Ron made a GREAT point also!! Your lucky to have only 117 volts AC coming into your home these days! At my location, I have modern-day AC voltages of 122-125 volts constantly into my home and workbenches! That said, I use a "variacs" w/ AC voltage meter aboard to "monitor", and bring up AC power slowly to power up many of my 1920s, early 30s vintage radios, and never let the modern AC line voltage exceed 110 volts as many,many, of my finest vintage radios would not like todays modern AC voltages supplied to my premises locally!!Randal
