Touché, Steve. I nearly replaced R32 with a 10 meg one which had been mis-filed. I measured the one I did fit to make sure that it was right and have just checked it again.
The resistors and capacitors marked in red on the diagram in post 51 have been changed. The ones marked in green are within ten per cent.
The HT is 256V of which 185V is making it to pin 9 and 70V to pin 7, which I think is the anode. This seems darned low but I haven't yet been able to find a decent data sheet for it so don't really know.
It opens and closes OK; it's just very dim overall. As I said, if it were only the EM80 that was like it I'd be happy to conclude that it was just past it but the EM81 is hardly any better though is very bright in its own set.
