A simple Valve Test Jig

[oceanobsession]

Thanks alan , ive got a fluke multimeter , and a twin power supply 30v 2 amp , 2 meter jobbie , soldering iron , I can make the case and cut out the holes no problem

its my knowledge that is lacking a bit , I'm looking to test the el84 valve 
is the transformer you recommended 270v  dc  or  ac  

I think the test conditions for the valve are
6.3 heater
250dc
250dc
7.3 neg voltage to control grid

and I think some resisters are needed to take the measurement in mv

Thanks for your help ill come back when ive educated myself a bit more
