AK Model 42 Transformer Ground?
#12

Referring back to Phlogiston's reply, "Remember the 850 volts," I ran a no-load on the secondary HV windings.
With 110VAC in, I get only 350 volts out. Are my connections actually to one end of the winding and to the center-tap ground? I have a lot of Atwater Kent data, but I haven't found anything about this transformer.

Is it likely that I should have 600 ohms across the HV winding and 700 volts output? If so, then I'm still looking for a missing connection, but to one of the ends of the winding rather than to ground.
