Hi apERNA,

Me again.

The terminal that the wire coil end of C402 401goes to is likely the terminal on the trip that is riveted to the chassis. Do make sure that that rivet is not loose or corroded.  The resistor you describe also goes from the
B- / heater string "Mecca" to chassis ground.  This is needed, because the cap stator and frame and the IF cans have to be at ground potential, as well as the metal bases of the Loctal tubes, as any shields used on the tubes have to be grounded, and they are grounded through the base.

Try what I suggested before about changing the electrolytics, put the antenna back on the parts chassis, jumper the switch, make sure that the chassis is at neutral potential and fire it up.  THen compare to the other set.  If they both perform the same, thenthe problem is definitely through power.

BTW, there is usually a cap, C100, a 0.04uF cap across the power line downstream of the power switch.  If this cap is open or gone, this can increase noise.  The cap that you need to use is a Y2 Safety cap.  The cap is fused so if the cap shorts, the fuse opens to prevent fire.

Forgive me, there is a problem with the document from the Philco Library that I was using.  The document is for Model 46-420; the pic is of the "Hippo" cabinet, the chassis is a 6 tube job, the sectional schematics are likely correct, but the complete schematic is for a 46-200.  Can't write to Philco to correct it, the company does not exist, the buildings are gone and the engineers are in the afterlife.
