Quick and easy testing of the audio output for Williams and Data East pinball machines. Including, but not exclusive to System 9-11
Depending on which version, this can be placed on the J15 header of the MPU, or J5(?) of the sound board (see video). Good for bench testing, or diagnosing wiring / speaker issues.
The speaker is an 8 Ohm, 1 Watt, and is pretty versatile in testing most pinball and arcade speakers. I used one of these to test a Spy Hunter, though I had to install a male headed (which the space is provided) and jam the SH spade connectors on it.
