Older Fender amps use a black material as a substrate for the point-to-
point wired circuitry. What is this stuff, what's its proper name, and
where can I get some (or an acceptable substitute)?
The material is black, semi-flexible, about 3/32" thick, and I assume it
has high dielectric value. Probably very tolerant of high temperatures also.
I don't care if it's not identical to the original Fender material as long
as it works in similar applications.
It's called a terminal board or a turret strip. The ones used on the old
Fender amps were wax impregnated cardboard of some sort, but nowadays
("nowadays" in the geologic sense, ie., over the last two or three decades)
nice robust epoxy versions with far better electrical and thermal
characteristics are available. (At least that's what I used back in '75.)
