A capacitor in that position will have a small effect on the AGC timing.
You can learn how it works now that you will soon have a couple of bags of capacitors.
If you cut the old part out leaving long leads attached to the chassis.
Leaving the leads long connect all of the new capacitors + to + and - to - and connect them to the stubs of the old part.
You will get a value close to 100uf and if you quickly tune from a weak station to a strong station you will hear the distortion for a short time as the capacitor charges up.
You can go on to remove the capacitors one at a time and observe how the effect changes as the timing gets faster.
No capacitor is likeky make the set blow a raspberry sound at you.
If this does not happen there is a high value resistor at one end of the capacitor and a detector diode to test.
Fit the new capacitor perminently when done.
