I'm not too pedantic about the use of American terminology, although, like most of us in the UK, I am more used to the English wrds, having been interested in electronics for over 50 years. However maybe it should be remembered that 'tube' in this context means a 'Vacuum tube', which explains what the device is, if not how it works. If I ever knew why an Anode is called a 'plate' in The Americas, I've forgotten. Maybe someone will enlighten me. B+ for HT+ is OK as far as it goes, but what is, if it exisits, A+? On the subject of voltage terminology, I recall that 'In Your Workshop' (Radio Constructor many years ago) once had a quiz iwhich Dick asked 'Smithy', or maybe it was the other way round. 'What's High Voltage?' Seemingly it's what is referred to here in UK as 'EHT'!
