Hi Pinside. I have a new replacement Stern SB-300 sound board. Uses Panasonic Electrolytic Caps. All ICs in a socket. Thick 1.6mm PCB with 2 oz. copper. Works with the VSU-100 speech board. Works with original and replacement MPUs. Used in Ali, Big Game, Catacomb, Cheetah, Dragonfist, Flight 2K, Freefall, Galaxy, Iron Maiden, Lightning, Meteor, Nine Ball, Orbitor 1, Quicksilver, Seawitch, Split Second, Star Gazer, and Viper.
New MPU-200 to SB-300 wiring harness also available as an add on or available separate. This replaces the often damaged ribbon cable connecting the SB-300 to the MPU. Consists of two 16 pin 0.100" CHRO series bifrucon contact connectors. Pin 1 is marked on each connector and the circuit boards. Ensure pin 1 MPU goes to pin 1 SB-300 and etc. The second 16 pin connector would start at pin 17 and go to pin 32. Pin 33 and Pin 34 is left not connected. *** SB-300 board is compatible with an original 34 pin connector ***
