Thank you BWC54 for your response.
Here's an update - I just re-measured resistance for the power transformer leads to ground:
1. red/blk wire is 0 ohms
2. both brown wires are 50 ohms
3. both red wires are approx. 40 ohms
I'm attaching the pics you requested. I didn't bother measuring the transformer (yet) since I think it's working based on the current measurements.
Many thanks again for any advice that folks can offer.
