Well, thanks for all of your input for this old Philco !
I am finally back on it again. I changed the electrolytics. Checked the voltages using a dim bulb tester and they are pretty close. I injected an audio signal in the #42 and #77 IF tube and get plenty of volume out of the speaker.
I injected RF 460KC into the IF transformer and again hear the tone from the speaker.
PROBLEM: For testing the receiving function of this radio do I need a ground hooked to it's terminal ? I don't have a ground to use. I have a long wire outdoors for the antenna. I do not receive any stations.
While checking resistances, I'm thinking that the Osc. coil is open. This could be my worst nightmare !
