Hi Julian, I've got the valve/card list No 8, it is up tp approx 1175 card and is hand annotated to show cards to 1196(DY82) and 1197 (EL500). I also have details of the cards to be used when the unit was fitted with a Y8A base. This will also be copied to GMB as will the data on vards got, when like you I get some time to do it.
I had heard of the rogue cards/ re-issues, but not in the detail that you have given. I will have to check my duplicates to see if there are any differences. This of couse adds a who new dimension to card classification.
The way round the problem with possible transformer burn-outs that I have adopted is to fit 200mA fuses into each of the transformer taps that feed the HT selection.
I trust one of the Forum members will host all this data when it is collated.
