Vintage Synth Repair

Yes - these synths have the Fatar keyboard and they are notorious for this
problem.  You have to open the synth and either clean or replace the little
key contact pads.  Google Fatar keyboard repair and you will see detailed
instructions for getting to the contacts.  You can go to the Kurzweil site
and download manuals that should help you get the K2600 open.  I found
replacement contacts at midi-store.com.  There is also a Yahoo group on the
K2600  with some information and manuals for download.

Subject: [vintagesynthrepair] Kurzweil K2600; keys not triggering

 

  

Anyone have experience with a Kurzweil K2600(s)? I have one that has a few
keys that do not trigger on/off. The synth will produce those sound
internally (via Midi) and the keyboard is sending out MIDI aftertouch on
those keys, but not on/off at any velocity. This started with one key, then
that key came back to life. Then it went out a week later, now 2-3 more
keys. I have a suspicion it's dirt/dust/grit, but before I rip the thing
apart, I want to talk to someone who has pulled the hood off. I took apart a
couple old analog synths, but want to get some advice before opening this
beast. 

Any and all comments appreciated.
