Capacitor leakage tester beneficial for working on CRTs?

[el.pablo]

Is there any benefit to using a capacitor leakage tester (like the build from Mr. Carlson) to test caps on 80’s and newer CRT TVs and monitors?

I know ESR is a good test but am not sure about leakage for these types of CRTs. Any input is appreciated, thanks!

I would only see leakage in an E- capacitor as being a factor if it is being used as a coupling into the base or gate of a transistor or FET.
Be it utilized in audio amplifier, video amplifier, sync separator, vert or horizontal circuits.
