I'll mention a couple of fine points on the 370 that are different from the 70/70B that you currently have. The major thing is that the vol/off-on and tuning are on two concentric shafts. The original vol/off-on control is made out of unobtanium. A single resistor and pot combo (sold as a replacement) doesn't really preform same way the dual pot does.
The dial and drive has a couple of pot metal gears. Haven't seen any failures but I have seen some swelling which makes the tuning knob hard to turn. There's an easy fix which is to slightly enlarge the hole in the gear on the dial.
Your a mechanical kinda guy and I just wanted to give you a little heads up before you dive in. Oh for autodyne detector hater this set doesn't use a single tube mixer like the 80,84,89,19, and so on. It has a 24A mixer/27 lo.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
