Yet another Roland TB-303 repair. This one came from a well-known artist and had a battery issue. While playing from battery it resets sporadically. It also did not always kept the patterns. I quickly spotted corrosion on the battery terminals. I ordered new ones and replaced these. While I was in here I replaced the tactile switches with new ALPS. I ordered a new battery cover which was missing and a replacement wall wart psu. That’s it, nothing serious, nothing special. But like always I took some pictures for my own reference and yours.
