Re: Measuring half wave voltages on Valve Testers.
Bill, AVO's, Taylors, etc only work on 20mS pulses from 50Hz sinewaves applied to valve electrodes. Basically - Full AC on the Anode, +ve h/w pulses on the Screen, and -ve h/w pulses on the grid.
Yes, they have an RMS component, but that's only used for calibration. Scoping the waveforms is the best way to understand. CT160's for example derive pulses from 2 separate t/f windings - 55V & 66V.
Just keep looking back over heaps & heaps of info via "Search".
