Ok. I figured it out. I feel silly, but this turned out to be a 220V model. I found this in a secondhand store many years ago and put it in storage as a future project without looking at it too closely. I realized after checking the voltages that I was getting only half the correct voltage on the output of the bridge rectifier. Is there some way I can swap out the transformer and make this a 120V device?   Thanks

I seem to remember it can be rewired internally. I don't have the servicemanual at hand now. Else: https://beoparts.com/2018/11/22/mains-transformer-220-240v-8013312/ Martin

I went ahead and bought a broken unit because I thought I would have to swap the transformer out. ? It wasn't very expensive, but I feel kinda stupid now. Is that what's going on here then? In the top configuration, the middle two taps on the device side legs are also going to ground, but on the bottom the middle two taps are no connection? I believe that my current configuration looks like the top one, so does that mean I have to cut off the 2nd and 5th legs of the transformer to get it to work? Login to view image   Thanks

No. That's two different transformers. Martin

Ok. Great. So maybe that means I did good by purchasing the parts unit with the correct transformer. It seems like I should be able to drop in the 2943 (120V version) into the space where the 2941 (220V version) is, and the rest of the circuit will be happy. Would you agree with that assessment? Thanks
