I put the cap in the radio and I get a little buzzing sound and when I touch the top of tube 75 I get a higher static noise and I checked the tube voltage on pin 4 of both 42 tubes and I get minus 1.6 dc v when radio starts to warm up and 0 dc v when the radio is warm and these measurements were taken from chassis ground
