Hi Bill,
Well the reason 5 has nothing is that 6 has nothing. The hv circuit is a little confusing because the band switch is used to short across the primaries of the 1st if transformer depending on whether it on am/sw or fm. Anyway I'd check the resistance of Z300 at the blue to red wires w/the band switch in the fm position. Should see a low resistance like an ohm or two. Then switch the band switch to am or sw to see if there is a high resistance there. Should still be low.
Happy troubleshooting!

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.
