OK Terry, your recent post mentions my early 116B and its output xformer.  This is a learning moment for me...if I'm unable to locate a period replacement and wanted to use a Hammond I think I could use either the Hammond 125D or E based on the 116B having a 10watt audio output.  125E would probably give a little margin.  Based on this (Bill Harris) online output xformer tutorial the load impedance for push pull 42s should be around 10k and with my voice coil impedance being something in the range of 1.25 or so (I think), I would want to hook up the voice coil to leads 4 & 5....??  Am I thinking that through correctly?
