Hickok 6000 Tube Tester Restoration - Complete Calibration Part 2 of 2

Continue the comprehensive calibration process for the Hickok 6000 tube tester restoration in this second part of a two-part video series. Begin with an oscilloscope test to check rectifier tube balances, observing both tubes' health without adjustments. Perform a grid bias test using a 50K shunt, aiming for 40V at 100 on the knob. Conduct additional bias tests with various shunt values, including a 10K shunt test and two 50K shunt tests, noting specific voltage expectations. Move on to the low screen voltage test using a 120K shunt. Tackle the bridge balance test creatively, utilizing a 10K 10W resistor and the gauge for measurement. Execute the gas test using a 6V6 tube (as a substitute for the specified 6L6) with a custom setup to short specified pins. Conclude the calibration process and demonstrate post-calibration tube testing, providing a thorough understanding of the Hickok 6000's restoration and proper functioning.
