IF oscillation in Philco 38-12
#3

Hi and Welcome,
Methinks you'll be just spinning your wheels till you get some new bypass caps in it. Also having a look at the resistors isn't a bad idea either. They drift in value. When that's done if the problem persists try detuning the IF transformer. After taking a quick look at the diagram couldn't hurt to add a .05 or .1 form red wire on the IF can to gnd.
