What a battle! The person working on this unit before, tried all kinds of 'tricks'. I found two extra lug strips for added components - stripped all that stuff out. Traced out the entire circuit and found missing connections to C305 and the connection between C305 to R304. Found an "extra" connection made to R300. R300 was open (severe overheating) - probably from that added connection. The FM was not working. After replacing the open R300 and restoring the proper wiring - FM now works. I've also had to change a Loctal socket. I noticed on both IF Amps, pin 3 had issues (??). AM Alignment is done. Something that surprised me was, for some reason, I thought the pushbuttons were for FM stations. I also had to return a number of open connections to the pushbuttons. The pushbuttons are actually for AM stations - makes sense now considering that era. At first I thought I had bleed over and then I realized that it was for AM stations. I still need to do a full FM alignment. I did the first steps of alignment to 9.1 MHz. My generator only goes to 20 MHz, so I have one on order. I'm doing this to give this to my son. Next I need to do some touch-up work on the cabinet (I am not a carpenter or cabinet maker).
