The TM-3 kit replaces the old keybed in any Sequential Circuits Prophet-600 with a modern Fatar semi-weighted one. This is the same keyboard used in many modern synths from DSI, Moog, Novation and many others. The TM-3 kit includes everything you need and requires no soldering, drilling or other destructive modification of the Prophet-600.
After the huge success with the Pro-One replacement keyboard kit, we decided to offer the same solution for the Prophet-600. The Prophet-600 keyboard is certainly more reliable than its little cousin's, but they were never really great. After 30+ years many of them are just too much hassle to keep healthy. Give yourself and your Prophet-600 a new smooth playing experience! The kit is very easy to install - if you have any questions just get in touch.
