I want to renovate the mixer, I recently bought one, the MAIN PCB was missing. ...managed to buy in the tascam ninja webshop. The unit works well, but when I took out the ROMs for inspection, a couple of IC-contacts were down. My question is that it is possible to get such ROMs from somewhere. I found similar ROM ICs on ebay, maybe I can just put them in and work? When turned on, the TASCAM logo starts, runs once, and stops. The mixer are probably looking for ROMs at this time. 1.
