Sega/Stern CPU/Sound board component update or repair kit.
Compatible with 520-5136-XX CPU/Sound boards.
Many Sega Pinball machines had their manufacturing costs reduced by omitting one of the sound channels from the CPU / Sound board. The sound portion of the circuit board was left with one amplifier "un-stuffed" with electronic components. The design philosophy was that stereo sound wasn't necessary for operation in busy street locations.
Now that many of these machines are in collector's homes, stereo sound can again be appreciated by installing this kit.
