Thanks Tom. I am thinking of the transistorized version with a 1k resistor in series with a push button to test to protect the circuit from a charged capacitor. Some caps even accumulate a small charge when at rest. Not that I would do anything silly like fry it with a charged capacitor.......I think that would be almost foolproof. As with all your videos, this one is really good. You and Don at Restore Old Radios have educated me more than you can know and I appreciate it.
That's a great high voltage capacitor leakage circuit Tom, I wonder if a DC Voltage Quadrupler Circuit would give you the 600 volts and you could have three voltage ranges.
Do you have a link to the original article for the low voltage/transistor-based tester? I built it from your drawing, and it works tickety-boo with any coupling capacitors, even showing leakage on 630VDC capacitors. But every single electrolytic I hook up shows up as a bright LED. Is this device not suitable for electrolytics? Thanks.
Fantastic video and great to see the upgrade on the original design Al .

Excellent video explanation and topic.
Excellent! Thank you very much sir.
I sure do miss me some Triple-T.
grate information tom
Thanks, as always.
Awesome work man!Can you recommend an affordable in circuit capacitor tester?
Good idea with changing out the switch...should keep you from getting a zing if you forget and grab the energized leads :)

Does the NE-51 bulb solder in place or does it use a permanently mounted twist lock connection?
nice video but please tell what wattage of resister you used in your tester to discharge charged capacitor
5 watts works perfect

very dangerous sir
