Ta Phil, could you post full sized images of
1) the "power factor" plate (the graph thing) and
2) the circular wattage thing which I presume is in the unit's lid.
Since the circuit is so simple I am thinking of a DIY version for my Avo7 and, if those images show them to be the same as those for a Model 40, then I can probably scan, and then print, the ones on my unit.
Andy, ah ok, the one I have has an aluminum plate/sheet as a facia but under that is a sheet of Bakelite-like or resin impregnated material which is about 1/4" thick.
