Once again your expertise is invaluable.
The power transformer secondary resistance reads a little low.  The schematic has half the secondary at 420 ohms and the other half at 400 ohms.  I get about 300 ohms on one side and about 345 ohms on the other.  The primary reads 18 ohms just as the schematic says it should and the filament windings read <.1 ohm.  Should it be replaced or is it within tolerance?

Einstein once said, "I have no special talents, I am only passionately curious."
