Oberheim Xpander - RES and VCF Fail Tuning

Hi All,

I've recently run all tests on my Xpander and the Res and VCF tests fail. Just wondering if anyone can recommend some steps to resolve from experience?

Thanks in advance!

Do all the voices fail? If only a few, I would start by swapping 3372s to see if it carries from voice to voice. Also, re-inserting the chips a few times (you don't even have to pull them out full) might help clean any oxidation (as mentioned above).
