A-112 sampler battery maintenance.

Like every other module, the a112 is something that can screwed into my rack, and made noise with, without needing ever really looking at its circuits again. At least in most cases. In my case however, when I bought this module used from someone on ebay, he helpfully included a spare battery cell. Which it turned out was for the best, because the module started misbehaving, outputting nothing but harsh noise.

Examination of the board showed that the battery had started leaking salty rusty ooze.

Doepfer must have been unprepared for this, because they chose to use a battery that is soldered to the board rather than some easier to replace form.

The actual replacement procedure is pretty trivial thankfully. Unsolder three pads, pull the old battery out, stick the new one in, and add some new solder. I’m no electronics genius by a long shot, but this was even within my capabilities.
