Hi TFonzart,

Divide and conquer. Add an aux input by breaking the connection between cap#38, resistor #39 and the output of the 2nd IF transformer. Connect cap#38 to the common of an SPDT switch, one leg to the junction of resistor #39 and the output of the IF transformer and the other leg to an RCA jack tip. Ground the body of the jack to the chassis. Inject an audio signal here. If sound, troubleshoot the rest of the set. If no sound, troubleshoot the audio and power supply section. In addition, direct injection of "old time radio" from an MP3, computer or CD player will make better sound than receiving AM.

When troubleshooting, make sure that if your set has push buttons, that the one for manual tuning is pushed in and is clean, and wired correctly. None of the bands will work if the push button for manual tuning is not pressed in and connection made.

Also wiggle the tubes, clean the socket contacts and tube pins and try to tighten the contacts. I have not yet experienced this, but many antique radio folks have run into trouble with loctal pins and sockets.

If you do not have test equipment, take a transistor radio, tune in a station above 1,000KHz, hold it up to the oscillator coil and tune the radio in question across the band. If you hear squeals or the transistor radio grows silent as the dial scale indicates a station about 460 KHZ below what the transistor radio is set to, then the oscillator is working.

Hope this helps.
