[sdiy] Key spring colors on ARP synths

[tamedogs at wildcats.com]

I worked there from early 1974 to late 1980.
Keyboards came from pratt-read. They came out of the crates, a guy named
Gene buffed the keys and into the units they went. I never heard anyone ever
talk about spring colors.

Subject: [sdiy] Key spring colors on ARP synths

Recently I have fixed some old ARP synths. They all needed a really good
cleaning of the keyboard. And as you know; you need to remove those key
springs to change key bushings and various other fixes.
The key springs have two colors; black and (dark) red. Supposedly because of
different tensions for the white and black keys, since they have slightly
different horizontal travel.

But here is where it gets strange:
Some of the synths I have fixed used black springs for black keys (sort of
easy to remember), while other synths used the red ones for the black keys.
So which is correct? Or did ARP change this according to any sort of
differences between the various versions of the Axxe and Odyssey etc.?

Anyone?
