This Akai S900 12 bit sampler came in with a RAM issue. Customer wanted me to replace the faulty RAM chip and socket them all. He also wanted to have a new display (that he sent with the sampler), PSU re-cap and a 3-prong mains power outlet. I tested all RAM chips and just found one bad ic. I replaced it and the RAM test was ok. Replacing the display wasn´t too difficult. Don´t forget to eleminate the old inverter 😉 PSU recap and new 3-prong also was a not too difficult job 😉
