A general rule among those of us who restore old electronics equipment to working order is "Don¡¯t waste your time testing wax coated and bumble bee capacitors.¡±? A bumble bee capacitor has color bands which give the capacitance value in pF using the same color code as resistors.

Just tried a few. Using an HP power supply that does 0-320V, with the current limit set low, and a Simpson 260 VOM on the 50V or 10V scale.
Seems to work well.
Here's a pic - good on the left, bad on the right.
Some of the 'bad' ones are perhaps marginal - a very small deflection on the meter.

BTW, I hope I didn't offend with my criticism of Carlson. He has every right to protect his I.P., to "sell himself", etc. I just exercise my right to ignore his content.
