Oberheim OB-8
Released in 1983The OB-8 is a wonderful analog synth with 8-note polyphony and two oscillators per voice. It has a switchable 2-pole/4-pole filter, an 8-note arpeggiator, and 120 program storage locations.
There were two versions of keybeds used in the OB-8; early models used a Pratt-Read keybed (K34U keys), while later models used a Matsushita keybed (K32U keys). It's important to determine which model you have before ordering any keybed parts.

We stock both NEW and USED parts; all used electronic parts are tested and guaranteed working.
This listing reflects our current inventory and is updated in real time. If a part is shown as Out of Stock, we typically don't know when or if we might have it again - but click on the part for more info, and then you will be able to sign up for an alert when we do have it available again. By including out of stock parts in our listings, we hope to offer customers a more complete and useful resource.
We cannot diagnose repair issues by phone or email. For technical questions, we suggest posting on our Forums, where our techs - as well as other users - can offer help.
