<p>There are several color variants of the springs. If I came
across blue and brownish ones. I am not sure if the colors where
used for specific variants of the keyboards. There are at least
two keyboard variants, the one with the metal key holders and the
one with the completely plastic keys. There is a slight difference
in length of the springs. When I take a keyboard apart I sort the
springs and when assembling the keyboard I start with the black
keys which is the lowest amount of keys and thus springs. <br>

<p>Yes there was a tool, you can see a part of it in the service
manual of the Moog Micro and Multimoog service manual. I made one
myself and it makes aligning keyboards much easier. <br>

<div>I think I once read about a specific tool for leveling
those Pratt Read keyboards that allowed pushing/pulling the
bushings posts without having to remove the keys. Or did I
dream this tool existed?</div>

Subject: [sdiy] Key spring colors on ARP synths<br>
<br>
Recently I have fixed some old ARP synths. They all needed a
really good<br>
cleaning of the keyboard. And as you know; you need to remove
those key<br>
springs to change key bushings and various other fixes.<br>
The key springs have two colors; black and (dark) red.
Supposedly because of<br>
different tensions for the white and black keys, since they
have slightly<br>
different horizontal travel.<br>
<br>
But here is where it gets strange:<br>
Some of the synths I have fixed used black springs for black
keys (sort of<br>
easy to remember), while other synths used the red ones for
the black keys.<br>
So which is correct? Or did ARP change this according to any
sort of<br>
differences between the various versions of the Axxe and
Odyssey etc.?<br>
<br>
Anyone?<br>
<br>
