It's been a while since I've posted.. the restoration is coming along. I ended up using self-healing, pulse suppression caps in the PS filter. as a fun side project, I built myself a nice little 6 volt filtered supply. the power supply is up and running well. I'm worried about what will happen should I need a new vibrator as I can't seem to locate the equivalent one that is in there. I've picked up a couple of philco universal replacements, but they don't seem to have the same pin out as the one in there.
I'm almost done recapping the chassis but I came across 1 that I need help in determining if I'm interpreting this correctly.
cap 20 & 21 is a dual .05 non-electrolytic. here's the blow up of the schematic.

on the original, there was a metal tap clamped in the middle which the 100 ohm cap going to the filament of the 1A4 tube. the left side when to ground. the right side goes to the I.F., Transformer.

and this is how I interpret replacing it
