Philco model 60 not tracking correct
#3

Put everything back in spec, micas and all. If your correct version schematic shows 410, put 410pf in. Start from the beginning again, check the dial position, down at 55, where does the aircap close - it could have slipped. Then apply your proper if frequency gen again and align the if, how strong an undistorted signal do you get out to the speaker, it should be quite loud, or peg the meter if you are using one. If all is well there, then begin with the rf wave through the radio. You replaced the if coil, was it right, connected correctly? 10kc off high, something not right and many ways to dial one in thinking you have the right adjustment, but it is a black art to dial one in correctly.
