Hi Joseph, here is a great article on various types of FM detectors including the FM1000…https://www.radiomuseum.org/forumdata/users/4942/file/FM%20Alignment%20Ghirardi%201952%20OCR.pdf

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!

Thank you! I was quite new to the Phorum when I started this post, so I feel like it might be advantageous to publish a summary of the process we went through in the Electrical Restoration category. I realize now that this thread should have been there, but that’s okay.

The abilities of our 'Phorum Pholks" never ceases to amaze me! Fantastic fabrication, Joseph! I'm waiting now for your PCB solution to the FM1000 tube scarcity. Come up with that and you would make A LOT of hobbyists happy! Take care and BE HEALTHY! Gary

Outstanding work indeed. I wish I could come up with solutions like this.

Joseph, this is beyond awesome. A lot of thought and engineering went into this and you hit a home run! Now I must save this thread for future reference. Thanks for posting!
