Could you post a picture of the Motorola “turned on”, so that we might see the dial markings after the dial changes?

I have several of those large portable radios, but most of them are the 3-way type, AC-DC and battery. I did build up a few AC power supplies for the battery only sets. The best way of doing it now is to use a 5 volt regulator chip.
I still have to build one up like that.
For a power transformer, I use a transformer from a scrap VTVM or other obsolete, worthless test equipment. Total line isolation!
