My 48-482 project
#18

Z404 was designed to be series resonant at the IF freq and without the inductance you may get insufficient bypassing and oscillations. After all, why would Philco go to the trouble of winding wire around the .01 cap if it was not necessary?

I left Z404 as is in my radio, as there is no significant voltage across it and it tested low for leakage. You might try winding an equivalent amount of wire around the replacement capacitor and see if it makes a difference
