Thanks guy’s! I will check it out this weekend. It is entirely possible that there is an alignment issue with the pot. There was no cardboard sleeve on the shaft as you mentioned.

Also, when I received the radio, the last restoration work was shoddy. The volume control was replaced with wrong valve linear taper pots, and its shaft was cut so a coupling could be used to connect the pots.

There’s plenty of evidence that the shaft on the selectivity control is installed incorrectly.

More to follow....
