Fisher 500c aquisition... with issues

Ok, I have finally done the required testing. Looks like I am in need of a OT: with the red wires (primaries) disconnected (as I received the receiver) T2 seems to measure fine as per gugusse's instructions. Resistance on Pin 3 of the 7591s is as follows: v8 - 118ohms, v9 - 123ohms. T1 however is a different story. v10 is out of limits on my Fluke DMM (i.e., open) and v11 is 122ohms. Oddly, however, when the primaries are connected, v11 is indicated as OL (but the display flashes and seems to fluctuate between + and - indication). V10 is open in either case. Anyhow, not sure what the meter is indicating here and the manual is of no help.

So am I correct in assuming the OT1 is pooched?

I'd guess so but maybe someone more experimented than me could confirm...
