Eric, it would be nice to know where your at now. You have static only which you can vary the noise level with the volume control?
What test equipment do you have? A signal generator or a scope or a signal tracer? It would help to check where your RF is being lost.
I suspect if you have static that varies in volume when you increase the volume pot, your audio section is just fine as is your power supply.
You could certainly have problems in the IF section with perhaps SMD or open coils. The only way to tell is to use a signal generator or signal tracer and find out exactly where you are loosing that nice sound. Once you locate where you loosing it, you can address the problem.
Resistance measurements of the coils in the RF, Oscillator and antenna sections would also help.
