I finally started working on my porthole. I thought it was interesting to note a mistake by someone working on this long ago. Look at the resistor in the pic with the arrow pointing to it, it's hooked to the wrong section of the can. What it did (now looking at the schematic) is to connect a 27K resistor parallel to that 20uf capacitor connecting to the tube side of the vertical output transformer. I wonder if this set ever really worked like that. Now I'm going to have to check over the whole set following along in the schematic to make sure there aren't any more similar mistakes.
