Important to test tubes after recapping a non-working TV or radio?

[Olorin67]

For the money you might spend to aquire and restore a good tube tester like a Hickock, you could get a stock of spares for most tubes. Can still pay to keep an eye out for em though, i found one hickok in an antique store for $40, and got another from a co-worker cleaning out his dads estate.
