I'm sorry Jon, but I'm not sure quite sure what you are seeking in terms of that tap ? What is the parameter you are trying to zoom in on to decide on connecting the ceramic? If it helps, I too should have that tapped coil sitting in the box of components which I took out of my HRO; are there any measurements I can take to complement your own?

@John KCOG; thanks for that info; I'll try track that article down.
