Are you still using the original tube? Maybe you have a bad one.
Have you tried all bands and all frequencies? Maybe you just got unlucky on what you tried.
Do you have an antenna? With no antenna you won't get anything.
Otherwise, it could be a misconnected capacitor. This can happen. If you have the philco documentation there is a lot that can be done troubleshooting wise. I don't have 1209, but the 1227 and 1230 have stage-by-stage test points to suggest you. at least half of it can be done with an MP3 player instead of a "audio sound signal". I know its not perfect, but worked for me on my 1230 before I got a cheap signal generator.
