I am the owner of a White sammichSID kit that i bought from another user on the flea market a while back and I've recently been playing with the synth again. I want to make sure its in perfect working order, and I have discovered that it is not. I have two problems with its functions: 1. When I received it, it was jumping values with the encoder as well as the up and down arrows. Is there a fix for that? 2. I also have a problem with the right chip in mine, sometimes it cuts out completely. Turning it off and back on again makes the chip start working again, but i've noticed that it has a slightly different tone than my other chip, despite being the same series. I'm capable of repairing this myself, I'm just not sure where to start to fix these issues. Can you suggest anything?
