Default Re: Valve testers & 'soak' testing.

Hi Folks, this type of tester could also be adapted to give a cathode peak emission test

With a fully warmed up valve the GB volts can be reduced for a few mS and the Ia monitored on a scope. This is a comparative test but "may" act as an indicator of remaining valve life ~ discuss.
