I picked up a used 2kxl with the 8 output board. The board is being seen by the OS but no audio. When the channel signal is turned up I can here the mono sample but it's garbled and distorted. I looked around on this forum and everyone is talked about installing the expansion wrong or if it's a mutecs. This is an akai expansion board and the R2 resistor is still metering continuity. I have loads of experience fixing vintage gear so has anyone experienced something like this or knows of a service manual for reference of what voltages and resistances that should be happening. It's my bet it's ic501 or ic525 on the fritz. Both fuses on the board are also metering continuity so any help would be greatly appreciated. Thanks!
