TM-8: Oberheim OB-8 | OB-Xa | OB-X Keyboard Replacement Kit
Compatible with all Oberheim OB-8 and OB-Xa revisions. The cabling is slightly different between 8 and Xa so please select which one you want above.
The Oberheim OB-Xa uses a j-wire Pratt-Read keyboard that is quite a chore to keep maintained. It oxidizes, causing non functional or double-triggering keys, and the rubber bushings dry out.
The OB-8 initially used the same Pratt-Read J-wire keyboard as the OB-Xa. After a while Oberheim switched to a Matsushita keyboard that was also used in MemoryMoog, Prophet-600, Polysix and many others. It has a cheaper feel but was more reliable.
No matter which OB you have, the keyboards are all around 40 years old now.
The TM-8 kit give gives you a brand new high quality keybed that is an absolute joy to play. Installation takes about 5 minutes and requires no soldering or modification of the OB. The operation is fully reversible.
The kit includes a Fatar TP/9S semi-weighted synth action keyboard, a black valchromat mounting plate, cabling + adapter card, and 5 M4 screws and hex key for assembly.
Note: The OB-X kit is still in development and we hope to release it in 2022.
