PostSubject: What is pushback wire?   July 28th 2015, 6:01 pm

i never heard this term before. I purchased an old book on math for radio,TV, and Electronics.
So I went on the web and one seller had this description:

Here's the right wire for Gibson and vintage-style guitar circuitry. 
The 22 AWG single conductor shielded wire has a tinned stranded conductor, white celanese and black waxed cotton insulation, and a tinned braided copper shield. The cloth insulation simply pushes back to expose the center conductor wire. ......

Diameter: 0.090" (2.29mm)
Length: 50 feet (15.24m)

This is the wiring that was commonly used in early TV sets and some radios.
 It was great since you didn't need strippers either.
It would also "push back" into the place the solder connection was made, often eliminating the need for spaghetti too.

  This pre-dates the thermoplastic wire that became "standard" in the late 50's. It also didn't melt or deform if you bumped it with your soldering iron.
