40-180 Voltage High

In many cases the voltages can be 20% higher than shown on the schematic. If voltages are well past 20%, then would suspect the audio output stage is not drawing much current. Schematic shows 180V on the plates of the 41 output tubes. What do read for the plate voltage on the 41 tubes? Check voltage on the 41 control grids, would expect about -15 volts.
