Thank you for sharing! I am going to take some time to review and soak this all in.

Just a quick update, folks. The PCBs have been manufactured, and shipped yesterday. Surely they’ll arrive this week. I also just submitted an order for the connectors I will need between the two PCBs. We should have a working IF transformer by the end of the week.

It works! I received the PCBs this morning in the mail, and put everything together. I reused the base from the original insides, and soldered the new assembly to it. Then I put the metal can on top. I need to complete the full alignment (at long last), but I was able to tune into a few stations quite clearly. And the nice part is that it looks original!
