Go back check plate and screen grid volts and make sure you cathode circuit grounded though the feedback winding.
Once you get the IF working again Try feeding a unmodulated signal into the cathode of the mixer tube 460kc higher than strongest station in your area. Tune the radio dial to the frequency of that station. Hook an antenna to the set and you should be able to hear that station coming from your set. The signal generator is acting as the local oscillator as you tune both the radio dial and generator you should hear all the stations you would normally hear.
