Well you should be hearing a 400cy tone. Try connecting the sg to the grid cap of the 78 tube and adj #4 for max signal at 460kc/400cy tone heard from the spkr. You didn't switch the 77 and 75 around?? It will fit but won't work.

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.
