What is the full scale reading of the Grid Bias voltage meter ? Thank you, Add new comment Comments 2018, December 17 - 11:03 #401385 Kari 13 years 10 months***** Do you have a Hickok (correct wroten) Tube chart? Values are between 0--43V usual - so I think FSD can be ie 50V. What states on the scale? BTW; maybe these help you some... https://elektrotanya.com/hickok_539c_tube_tester_calibration_sm.pdf/down...
