reduce voltage

Another thing to check is the negative bias going to the 45 tubes. If any of those resistors labeled 57 and 58 are open or increased dramatically it will also cause a large increase of voltage across the caps in the power supply. Resistor 59 in the cathode circuit of the 45 tubes is worth checking too. It could cause higher than normal B+. These resistors balance the loading of the power supply and should be within 20% tolerance.
