Next steps are to check the voltage @ the 6A7 tube mostly the plate, screens and cathode. If all seem reasonable check to see if the osc (lo) is operating. This can be done by setting the dial on the Philco @ 100 (1000KC or 1MC) and listen in with another receiver with the ant wire wrapped around the 6A7@ 1460kc or thereabouts. I'd give it about 50kc +/-. If you don't hear a loud hiss good chance the lo isn't working. Time to have a look at the osc coil primary. Look for small green dot(s) resistance above 20 or 30 ohms or no resistance (open). Oh and just for grins connect the ohmmeter across the osc section of the tuning cap with it complete open. Should read and a few ohms turn the dial and till it's closed it should read the same. If it drops you've got a bent plate that's shorting the cap out. GL

figure out what all those squiggly meant.
