OK, so I grabbed the online schematics for the Model 65, pulled the tubes and opened up the bottom. This is what I see:

Couple of new questions:
- Schematic shows 11 caps, I see 6. One steel box with one wire on left, 3 things that look like small photo tubes, 2 metal tubes the size of half a cigarette. Where are the rest? (The 11-count on the schematic don't include the 4 in the condenser box.)
- I also see 3 things that look like like the larger caps but are probably resistors (two metal rivets with wires, ground to case.) Are these resistors? If so, do these need to be replaced like the caps?
- There's a large tube on the right hand side of the pic, looks like two coils with a center tap. Looks like electrolytic corrosion on each end, and a small wire connecting the two coils at the center has dropped loose. I can't find this part anywhere on the schematic. What's going on with the corrosion?
I've grabbed a copy of an "old time" radio repair manual, and have ordered some more complete schematics. Hopefully that will clear some things up.
Thanks.
