Title says it all, am trying to get my bombjack board sound working so I was looking for a 51516 amp chip. While I was in the UK at xmas I found a UK place online selling them for not very much, except I was ordering from memory, and ended up buying M51518 chips not the 6's.
They arrived, I didn't notice my mistake, they are physically identically so I soldered one in. It didnt work, soldered the other one in, it didnt work, took the 51516 off my Armidar board and put it on bombjack and it worked. Put one of my new chips onto my armidar board - no sound. So I thought the chips were both faulty.
It was then I noticed the faint markings on the chip itself and found my error. So have ordered some 51516 chips but my question is....
... anyone have the datasheet for the 51518 amp chip? Even the pinout would be handy, or if you know of an arcade board that uses it I can work backwards from that if the schematics are around.
Mitsubishi say its too old for them to have records of it, google throws up nothing at all. It clearly isnt quite pin for pin compatible with the 51516 as it didnt work, but there was no bang, the chips didnt get overly warm so I am hopefull I havent killed them, without info on the circuit they expect I can even test them tho.
