Re: Hypothetical EHT Question.
The unrectified flyback EHT would be negative during the scan and +ve during flyback - so no picture. However the capacitance of an aquadag'd CRT loading the LOPTY would no doubt wreak havoc.
As for the AC EHT, at lower +ve EHTs the scanning angle would be so wide that at some point the electron beam might well hit part of the gun structure and cause heating, but whether that'd damage it I've no idea.
TTFN,
