I normally do a quick but cautious 'viability check' on vintage radios before I start spending money on it.

However I have never tackled a valve TV.

Apparently you can do a simple cathode emission test on a monochrome CRT (assuming 6V heater) using a 6V power supply, a 1K resistor and a multimeter.

Does anyone on this forum do simple tests like this before starting a full TV restoration?
