transformer needed to isolate the chassis was an expensive component.


The standard all-valve "large screen" TV of the 50s/early 60s consumed
150W, of which half went into keeping the heaters alight. So a 250VA
transformer would have been plenty big enough.

Even so that was a very expensive component and the way TV design was
costed to the nearest fraction of a penny made it a no go!..


My first generation colour set was 500 watts. And due to the rectifier
loads a 1000 watt isolating transformer would have been more suited.

Must've been a G6 then?...
