After work jam with the 303 & 606
The client had a TB-303 which did not work well when then Sync-cable was inserted. Intermittent jack was the problem.
Fixed the flakey din-sync jack by unsoldering, removing the clear plastic protective cap, and cleaning the corroded switch. Take good care of this jack, because you wont find a new one. Normally the 303 plays from the internal clock. When a sync cable is inserted it activates a switch that changes the sync to "in"-modes. If this jack breaks it has to be replaced with a normal jack, and then add an in/out-switch.
Also replaced an intermittent tact switch. A 303 with bad switches is no fun at all. Played it with the 606 and now it jams again :)
