Doing a little homework before my next ship trip on Saturday, and the plan is to start working on the poor Model 28 #2 to bring it back to life. The harness in this thing is pretty trashed (chunks were cut out) so I'm doing a little model 28 learnin so I have a better idea of what I'm looking at. I have a bunch of manuals and diagrams thanks to Nick's site, but I didn't see this mentioned in the basic wiring diagram, and other docs just mention it as a transformer and nothing else.

On the LESU there's a transformer and cap (lower left in the pic) - I believe this may be the "selector magnet driver", although in this unit (which is Navy UGC-48A), I'm not sure it was needed due to the other electronics. The part number on the transformer is 158286.

Is this considered a local loop supply?
