Repair Akai S900 12 Bit Sampler

Akai S900 12 bit vintage sampler. Common 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 ;)

There are lethal voltage exposed in electronic devices. Unless you know what you are doing, don’t try this. If you following along, you doing so at your own risk.
