Thanks, Ron. The switch has three distinct clicks, which threw me off. If I'd looked more closely I would have seen only two bands on the dial.
I did a quick attempt at aligning the radio and did finally get stations across the entire band. Once I have the specific alignment instructions it ought to be fine. The IF was WAY off. I adjusted it to 460KC and things kind of fell into place. The coils were rewound at some point and I was afraid that they were too off to bring it back.
I tried to upload some pictures but wasn't able to figure out how to do it,yet. What I wanted to show was how the previous restorer converted two tubes--the 75 and 78, to two different tubes by removing the guts of the 75 and 78 tubes and soldering the leads from the newer tubes into the base of the old tubes. It looks terrible, but I have to give the guy credit for preserving the original sockets for a future resto. Was this a common practice back in the day? The tube shields hide the mods, but you can't help but cringe when you look at those tubes suspended in air above wires and the old sockets. You're right, though. This is going to be quite a job to bring it back to original condition.
