Surprisingly, I thought about that and used a piece of cloth as a buffer! All the leads have the correct voltage according to the schematic. Unsure why that transformer is thumping mechanically and the other isn't. Loose core? I have a nice scope, and would check the AC waveform coming from the transformer leads, but what would that show? Anything?
