You didn't throw anything out of whack there with those cap replacements. Sounds like you have to start tracing the wiring against the schematic to be sure your re-wiring is correct. Osc coils, bandswitch, etc.

If not even a 470 kHz modulated test signal from your sig gen is getting through to the audio section, you have a problem in the detector and or IF. If you do hear the modulation tone from your gen through the IF, then the fornt end has the problem.
