Thank you Ron...yes I removed the bottom and saw the coils in the 3 large cans and I have saved the first installment in the 65 restoration series as a favorite. I'll be referring to it and all of the subsequent parts as I go at this beauty. Since I'm new to the forum, I assume you are Ron of Ron's Radios? If so, the website is fantastic with great documentation of restorations. So the capacitor can in front of the transformer is where 4 capacitors live? It's part 3515 and contains 0.15, 1.0 and 2 2.0 caps? I measured resistance from the 80 tube to ground and got about 180 ohms on both leads (plate and filament?). What else should I do to test the transformer? Again, as in my other threads, forgive my stupid questions and electronic vocabulary as I'm new to the hobby and this forum.

Yes...I am indeed your charming and delightful Old Uncle Ron.
(Bonus points if you can name the DJ from whom I "stole" that description of myself.)
Thank you for the kind words.
Yes, the large can contains the two 2 uF caps, the single 1 uF cap, and a single 0.15 uF capacitor.
As for the transformer. If you are getting approximately 180 ohms between each 80 plate and ground, you're well ahead of the game. Test the other windings for continuity.
You'll notice in my blog posts that I rebuilt my transformer by adding new heat shrink insulation to its wires, especially the three rubber-covered leads which come out from inside the transformer. This is not a job for a novice. If you don't really understand what you are doing or do not feel comfortable doing this,
seek help from someone more experienced. You're in the Philly area, lots of radio collectors around there including a few who frequent this Phorum.
