ARP 2600 restoration completed
YouTube via MusicMiK. follow-up to this post
"The last part of the ARP 2600 restoration video series.
Fixing the keyboard was the harder part of this restoration, i completely took it apart, cleaned everything, removed some rust, replaced the bushings and adjusted everything. Works quite fine now.
What you don't see in the video - i added a small circuit as a CV/Gate interface, which emulates the keyboard, so you can still use the portamento on your CV input and the trigger behaviour is exactly the same as with the original keyboard. This interface accepts TTL gate signals, so no problem with the 15V, you usually need on the ARP 2600. Schematics and layout will be published on mik-music.org after some minor corrections.
The whole restoration took about 50 hours of work and i really wouldn't do it again - except on my own 2600, if i ever get one :) Sure, it could have been done faster, but the motivation for this was curiosity and the challenge to get this done as good as possible :)"
