You will not find any 1N4008 because they are not made. And post #4 is incorrect about the scheme for diode numbering. And what is an "EHT" rectifier? Not familiar with that acronym.1N4007 are 1KV. Will have to be in series. No 1N4008 after scanning 4 CRT TV cadavers in my junk... Just the mentioned one.
OK on "EHT", not a term I would use. That would be the second anode high voltage diode, often embedded into the horizontal output transformer. That would be a good alternative if it can be recovered. I have not tried to do that. Those devices seldom fail.hi,
Extra High Tension.

EHT is extra high tension - (extra high voltage in modern terms).And what is an "EHT" rectifier? Not familiar with that acronym.
EHT was a familiar term for final CRT anode voltage used in the UK when I took my training!And what is an "EHT" rectifier? Not familiar with that acronym.
I gave that some thought also. When replacing some of the old vacuum tubes or valves (for those across the pond) the forward voltage drop might be a consideration but the more I thought about it I doubt it matters much in this application, with a vacuum tube having a 6.6 KV inverse plate voltage.The 1V2 has a voltage drop of 135 volts at 7mA. This may be an issue
