Philco 17 SW band not working
#8

To parallel Mike's comments if just the osc is the fault on the sw band you can try this as a troubleshooting technique. Set your radio dial at 1700kc. Set your generator at 1875kc without modulation. Turn the output down fairly low and connect it to the grid cap of the 6A7.

If all is well but the osc you should be hearing WJCC. What we are doing is substituting the generator for the osc. If you keep the generator frequency 175kc above the 17's dial frequency you should be able to track all the way up to 4000kc with the generator at 4175kc.

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!
