Hi Peter, from what I remember of the theory, the autotransformer "tap" went to the CB terminal, so that at points opening there was a "lift" of about 400V on the tap, giving a little bit extra to the 25KV or so at the HT terminal.
I'm not sure if that is better than having a hot emitter spark plug tip or not.
