LinnDrum with some issues. The 5V rail was way too low to constantly work correct with TTL. Once I adjusted that the LinnDrum worked just fine. But... there were some other issues like caps that needed to be replaced, buttons that needed cleaning. So it turned into a full restoration job.
I found physical leaking matsushita capacitors, some way out of tolerance
None of the potentiometer/switches were cleaned. I took over the restoration process.
