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.
GAME APPLICATIONS
1995-1996 Sega Pinball games up to and including GOLDENEYE have two backbox speakers and a lower cabinet speaker, and run in true stereo. All 3 audio amps are populated on the CPU board and this update kit is not required. These games are:
1995-01 Mary Shelley's FRANKENSTEIN
1995-02 BAYWATCH
1995-07 BATMAN FOREVER
1995-10 APOLLO 13
1996-03 GOLDENEYE
Late Sega and Stern Pinball games from LOST IN SPACE onwards have two backbox speakers but they are effectively mono as they are both connected to the left channel audio amp on the CPU board. The right channel amplifier circuitry is un-populated. These game are:
1998-05 LOST IN SPACE
1998-06 GOLDEN CUE
1998-08 GODZILLA
1999-02 SOUTH PARK
1999-09 Sega HARLEY DAVIDSON®
