Hi, oh good. glad you got most of the pieces figgured out. i found that the
voltage rating on the Mot or diag. usually refers to the voltage the tube
runs at. measuring the output unloaded might give you a better reading to
work with. be carefull those Mot's are as deadly as a pole pig....cul brian
