After reading your responses and some more thought, I decided to go the route Codefox suggested. I wrote down a parts list from the schematic, and looked at it. Something didn't seem right to me... Before you guys start laughing, bear in mind that I am in my early 30s and all my knowledge is based on Navy training for modern components.
Looking closely at the list, I realized I didn't have a single value below 1 Megohm!? I thought "That can't be right, why would there be 470 Megohm resistors in this thing?" A little Google-Fu later, and I now know that the annotation of M Ohm in the old schematics is notation for thousand! No wonder everything looked funky to me!
Armed with my new knowledge, I will replace all the resistors in the set. I didn't trust any of the paper caps, why would I trust old carbon resistors.
This brings up a new question. The candohm resistor has one 220 ohm section reading way too high. I have 10W power resistors to make a new one. Is 10W enough dissipation or should I source higher wattage? Is 10W too high?
