38-12 Oscillator Replacement
#11

Yes that is the proper schematic for your set. If the osc is working and the dial is set @ 1000kc you would hear the osc signal @ 1470kc on another receiver. It will unmodulated so there isn't any tone or voice just a loud hiss.

You may try reversing the B+ and screen grid connections. The phasing of the windings is important. If it's out of phase it won't oscillate due to a lack of feedback. According to coil info it's wired correctly but...

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!
