Roland IR3R05 Filter IC Chip (Quantity 1) NOS Three Available I own Synth Tailor Electronics which is a vintage synthesizer, drum machine, outboard gear repair shop based out of Columbus, Ohio. These are from my stock originally from a Roland authorized repair shop that closed down years ago. They’re all NOS, never used before. I can verify they work prior to shipping if you’d like. These will work in Roland JX8P, JX10, MKS50, MKS70, MKS80, Alpha Juno 1 and Alpha Juno 2. No returns!
