1937 Philco 37-610 Electrical Restoration

This is a view of the bottom of the IF section sub-chassis.  Since I had decided to replace the wiring, I took the entire main chassis apart, making it easier to work on the individual sections.  Here I have replaced the front and rear chassis panels.
IF Chassis:  Here is a close up beneath the 6Q7G 2nd detector/1st audio tube, and the 2nd IF transformer.  All the caps and resistors were replaced throughout except for one mica capacitor and two resistors buried in the tuner section.

Here is a view of the power/audio sub-chassis.  
Note that I spliced in new wire to the transformer leads and used a lot of heat shrink tubing.
The original phenolic grounded solder lug broke, so I fashioned one from a piece of Radio Shack phenolic circuit board.  I reused the original lugs riveting them into place.
Since I did not reuse the bases of the metal canned electrolytic capacitors, I needed additional lugs for connections, so I used another piece of circuit board bolted to the other bakelite capacitor block.  In retrospect, I will reuse the bakelite bases to the metal canned electrolytic capcitors next time so I have something to solder to.
The 6a8G tube socket in the center sub-chassis for the tuner/oscillator section is hard to access.  I removed this sub-chassis and then removed the two side panels from the assembly.  This allowed me to remove the two paper capacitors from the socket pins and replace them with new smaller sized capacitors.  Since they both go to ground, I installed the new ones directly beneath the socket instead of across the chassis as was previously done.
I have installed the dial in front of the metal tabs for fear that the tabs might scratch the lettering on the front of the dial.  The dial is not warped.  I don't know if the tabs should be in front of the dial to guide it.
I believe the paper cutout is to prevent the band changing lever from scratching the back of the dial, and therefore installed it in back of the dial.
