As I remember from the previous experience with the 45 chassis (I restored it for Kirk 2-3 years ago), the phenolic panels were not very convenient. Even when the screws are removed, the wires and parts soldered from beneath hold it from easy turning, so extracting parts, if one wants to do it neatly, is a bit laborious.
The tubular paper caps I have have rolled ends. This is the second time I encounter these. Even though the extracting the cartridge did not pose much problem, the unrolled end has to either be cut or potted over as is. I prefer to cut but then it depends on the length of the inserted film cap: for 0.1uF the cap is long and the cut tube does not have enough space for it inside to have a wad inserted (even if I re-use the fiber washers that are there). Of course I could've used smaller caps but I only store one type, 630V film by Illinois capacitor and those are fairly good size.
The resistor in question (the one absent in the sch or in Buzz' radio) is authentic Philco and the soldering was all original factory, so I want to see if by chance the speaker's FC resistance is a bit lower and maybe they were trying to lower the overall B+ for every tube by loading it with some extra resistance. I doubt the rising AC voltage had anything to do with it.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
