Working on my recently acquired 2B - sn 10422. All of the DC (B1 - B4) voltages are about 12% low. The plate voltages on the 6X4 are about 160 ac - about 10v high. I've replaced the electrolytics with new ones, readings were about the same before I did that. Any ideas on causes, there's no obvious burned resistors, and it seems to work pretty well. Thanks Paul W2LE
