Depends. We need to figure out which isn't tuning properly. Use a counter or another receiver to track the local oscillator frequency and see if it's tuning low enough ( it should be 455kc above the in coming signal . To receive a signal @ 560kc the osc should be running @ 1015kc). If that isn't working properly check 23 and 24 for correct tolerance. This is assuming that the switching and wiring is as it should be.

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.

Now I think I've got!
