I'd be verifying that it's not the transformer at fault as you know the wrong voltage is comping out of it, but you didn't say what was going in. I believe the tap numbering is listed in the service manual.

Also verify your entire bank of fuses are good with a continuity check. Sometimes when I get weird voltages on a feed circuit it's a cartridge fuse that's gone bad.

Thank you for the reply! Based on my reading, a reading below 1 (which in the case of this inductor, it is at or slightly above zero) means a bad inductor. But I'm willing to take other advice on that. I did not test the transformer. I only tested the output on the ACRY unit board on the posts where the transformer connects. The service manual shows there should be 120VAC there, but I only read 47VAC. So, that's 47VAC going INTO the transformer.

I have not checked all fuses on every board, but only the one fuse on the ACRY board. Continuity on that fuse checks OK.

I attached an image. The posts in the red square are where I tested and showed 47VAC rather than the 120VAC as stated. That CN550 connection is where the transformer attaches.
