ROLAND TR-909 service

Outside the TR-909 drum machine.

I recently had the pleasure of looking over a TR-909 drum machine. The owner was experiencing intermittent problems after storing it for some time. After checking some previous repairs (prior owner) and touching up/ cleaning a few things it was working perfectly. Nothing much to report!

You can see the (desired) noise content anyway.
