How to Make Bias Probe Bases Out of Bad Vacuum Tubes – IMPROVED METHOD

Posted on December 10, 2021 by roger

Don’t throw away your bad vacuum tubes! Make some bias probes instead. This probe is a step up from the ones I’ve made previously because it has a tap for the cathode. This facilitates plate voltage measurements for cathode biased tubes without opening the amp. You can also get screen current measurements and cathode resistor voltage drop measurements without opening the amp using Ohm’s Law calculations.
