After a check yesterday evening, I got ~100 ohms on the primary side
across the entire winding (ST-70), I did not disconnect any wires to
measure. So, based on a guitar-amp, I would expect your measurement to
be just fine. I did not get a chance to measure the Scott as I had less
time than I thought.

However, this evening I will have more time, and I will use the Fluke
meter rather than the R/S glove-box unit.
