Hi all,
I have an old Philco 42-322 that powers up and works great. However, I want to try to restore and modernize it by adding a Bluetooth board using the method from this website so that the audio will still play through the original speaker (which is in great working order). Admittedly I’m not as knowledgeable about this stuff, but I used this same method to add Bluetooth to an antique Westinghouse radio a while back and it works great. However, now that I’m trying to do the same to the 42-322, I’m struggling to figure out the correct wires I’ll need to disconnect to run new wires to the Bluetooth board, and I want to make sure I’m looking in the right place before taking anything apart. Would anyone be able to offer guidance on the correct location for the speaker solder terminals, as well as the correct wires to remove and replace on the potentiometer soldering terminals? I’ve tried looking at the schematics and just haven’t been able to figure it out, so any help would be greatly appreciated!
Thanks,
Nate
