CPU/Sound Board component update kit

#520-5136-SK

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

1996-1998 Sega Pinball games from TWISTER through to and including VIPER NIGHT DRIVIN' had only the left side backbox speaker and the lower cabinet speaker. The additional speaker is available separately as listed below. Only two of the 3 audio amp circuits are populated on the CPU board. These games are:
1996-04 TWISTER
1996-07 INDEPENDENCE DAY
1996-12 SPACE JAM
1997-03 STAR WARS TRILOGY
