Sounds like you may have an open antenna coil or open RF coil (just before the 1st. Det tube). Inspect the solder lugs on the coil forms for corroded or green spots where the fine wire connects to the lugs. Any greenish areas in the windings also indicates where corrosion has taken place. Coils can easily be re-wound. See this Service Tip on my site for guidance.
