Hello

To answer people's questions (in no particular order......)

Yes I plan to do an alignment.   I have a signal generator and scope (of course.....)

Yes, that's how the AM BCB sounds here.

Spent some time tonight trying to secure that bent antenna terminal.   Had to be very careful as there is almost no room to fix the connection if it breaks behind the front panel;  I had to use a very slender needle-nose pliers to crank the nut down as best I could.    The connector still isn't straight, but it's snug.

True, especially for the small tweak required.
Check the IFs too. Better if you have a Sig gen, though...

There's complete instructions on alignment via original manual material for the 946B. I did mine & it was a cinch. Putting all the case screws was more tedious. LOL

If I recall correctly you calibrate the oscillator to track by adjusting a trimmer capacitors on the tuning capacitor and the oscillator coil.

I would first check the tracking as it is. Old school method is to use a frequency meter or tune in AM broadcasters.
