TB-303 Complete Keyboard PCB, Roland

This keyboard PCB is designed as a direct replacement for the original keyboard board of the Roland TB 303. It is supplied fully assembled and soldered, allowing a quick and reliable installation while preserving the original feel and visual behavior of the Roland TB 303 vintage synthesizer.

For RE 303 builders, this keyboard PCB fits directly into our TB 303 reproduction cases, with no modification required.

High quality Alps switches are used to ensure precise response. The LEDs are specially selected with low brightness to faithfully match the appearance and behavior of the original TB 303 LEDs, without the overly bright look of many modern replacements. Original Rohm transistors are fitted, ensuring electronic characteristics consistent with the original design.

The PCB is manufactured using a modern rigid material, preventing the warping and mechanical degradation commonly found on aging original boards.

New ribbon cables are supplied, with extra length to make installation easier. Replacing the complete keyboard PCB significantly reduces service time compared to repairing an original board, offering a solution reliable for bringing a Roland TB 303 back to perfect working condition.

Included:

-Fully assembled and soldered complete keyboard PCB
-New ribbon cables
-Two additional ribbon cables included
-Connection wiring
-Plastic PCB mounting supports

Important installation note
It is recommended not to desolder the ribbon cables from the mainboard, as this may risk damage to the CPU. When possible, the original ribbon cables should be reused and connected directly to the new keyboard PCB.

This keyboard PCB is intended exclusively for the Roland TB 303 bassline synthesizer.
