I had a transformer given to me by the guy who actually wound and tested them at AVO. I have measured the windings for my own purposes and find that the taps used for the capacitors should be 14, 18 and 23, if they are to have equal voltages across them. Personally I will be fitting two 1uF "X" capacitors, using tap 18 only.
I can make this data available to anyone who wishes.
