Help needed for a Philco-Tropic Radio, model 3000, code 121
#7

Hi,
Oh you mean the .002 MF cap. Sorry I'm kinda old school w/these cap values. I would replace it as wired. Looks like it's in series with the ant to isolate the ant coil from chassis gnd which has some relation to the ac line. The blue wire is your ant wire which connects to your outside ant.

The green wire if it has no other connection at the terminal strip than to the spkr it's a test point to connect an ac voltmeter when servicing/aligning.

The short green wire that is soldered to the tuning capacitor trimmer should only be soldered on one of the trimmers, not both. The unsoldered end should still have the insulation and just slip thru the trimmer cap's lug hole.  It's used as small (in mmfd) cap to couple a little oscillator signal in to the input side of the mixer.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts

figure out what all those squiggly meant.

Now I think I've got it!
