Model 42-321 wavetrap

The .2 cap is the b- rail ground return to the chassis. The inductor is a choke to discourage longwave signals from interfering with the IF stage at 455KC.
Since we don't have much if any longwave signals these days the choke is unnecessary.

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 it!
