I'm working on a 41-608 for Sam. I just have the chassis and spk. Was doing the rf alignment and noticed that the BOL is coupled to the receiver's local oscillator. There is a trimmer to adjust the frequency but I didn't see any spec as to what to set it for? The coupling coil is the bottom one on #9 and trimmer is #11. Not quite sure why the pickup needs a rf signal to operate?

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
