The power supply was rebuilt,and all of the coupling caps were replaced.Only about a dozen of the resistors were replaced so far.On V1 at pins 1,6 I am measuring 86v where it should be 103.On V2 pin 2 is 85v but should be 103,pin 7 is only 30v but should be 85v.On V4 pin 6 is 314v but should be 430v,pin 2 is -24v vs.-46v.Tube V7 pin 2 is -24 vs -46v.Pin 6 is OK at 423v vs 430v.The 6L6 tubes are measuring close to spec.voltages,as are the 12BH7s.Any advice on what to check first would be appreciated.
