Review on Nobsound Vacuum Tube Amplifier Bias Current Probe Tester | 8 Pin Socket for EL34, KT88, 6L6, 6V6, 5881, 6550, KT66, KT100, KT120, 7027 (CT1-C, Cathode Current) by Kristi Green
Works as it should, great price!
Plugs directly into my Texas Instruments voltmeter and does exactly what it's supposed to do. If you're swapping tubes, oh, it's important to preload the power tubes.
