Another Ebay "works Perfect"
Anyway this one had no sound, checked the Z80 and clock / data was there looks like someone lifted the ROMS out of the socket (minor damage) so someone knew there was no sound at one stage.
Followed the data up through the OKI chip then on to the Yamaha sound all OK so far, Hmm check AMP, getting power OK, getting warm OK, touching the amp circuit with a finger produced no static. Probed further to the output no activity.
Used a multimeter to check continuity between the JAMMA connector and the AMP and noticed that one of the pins on the resistor packs things was never soldered from the factory could it be this simple?
YES! It looks like from the factory it worked but over the years tarnishing has reduced the pitiful contact to nothing, resoldered and audio came back. Still dont like Ebay for sellers testing properly. STATUS :- FIXED.
I would also like to mention this game is ectremely fun, plenty to destroy in the background and very intense on hard. After I played Cabal this was a welcome game to see.
