I replaced all the axial caps underneath and one that's on top where the tweeter connects. The new caps are all Illinois Capacitor, 630v. The little "black beauty" striped cap that was on the left connected to the volume pot is .01 µf.

I powered it up and got some nice sound on AM but nothing on FM as I didn't have the antenna connected (hopefully that's the problem).

I'll probably change the blue thing this weekend although I'm pretty sure I don't have a larger value resistor (one of they guys in my thread suggested a 33 ohm to change the 22 in place). And, I did get new caps to replace the multi section cap. Nich 160v,100 and 47 µf.
