Default Re: HT transformers with extra low-I higher-V winding - what were they for ?

Hi GJ, the higher the EHT on a scope the higher the deflecting voltage needs to be (for older scopes without PDA).
Typical non PDA scopes needed a mA or 2 for the tube current and divider chain; PDA normally need sub mA

No idea about flat bed recorders, would depend on the amps used I suppose and writing speed. I doubt much would be needed for ES hold down
