Here's the underside of the patient. Again.

In case you have forgotten or did not read page 1 of this thread, the paper capacitors have already been restuffed with new caps.
I don't know if I have ever mentioned this or not, but over the years I have developed my own system for unsoldering the wires of a 1937/38 Philco RF unit, and then soldering them back up again. It has worked well for me over the past few decades, so I see no reason to change now.
I make a drawing of where each of the wires go that come from the RF unit, making careful note of just where they connect under the chassis. I then number every wire. I think those wire labels would be dandy, but I've never had any of those, so I just make dots on each wire corresponding with the proper number. One dot = 1, two dots = 2, etc. Once I get to 11, I make one dot, leave a space, and make another dot. 12 = one dot, space, two dots. And so forth and so on.
I have a notebook in which I keep all of these drawings. Now, I had to tear this one out so I could scan it, so I will probably draw it again and keep it in the notebook.

I make no claims to be an artist. It's a bit crude, but it works for me. This will help me reconnect each of the wires correctly.
Yes, there are two wires labeled 7. They both connect to the same point under the chassis, so I assigned the same number to both.
The drawing also shows the speaker wiring harness. I've made a new harness for this radio, I just need to install it. This drawing will help me do that.
I have now unsoldered each of the wires and removed the volume control shaft as it needs to be out of the way before the RF unit is removed. Tomorrow is a holiday, so I will disassemble the dial assembly and remove the RF unit in the morning, and we'll see what happens from there.
