Re: [Fairlight-CMI] restoring a Series IIx
2007-11-29 by Harald Feldmann
Hi David, I find the picture a bit odd, the battery is supposed to be on the round part which is at the bottom of your picture. The part that looks very corroded is the crystal. It would seem to me that the crystal is covered in oxide. **If it worked before like this*** , maybe just clean it up a bit and remove all the conductive powder that comes / came off of it ? Still it is odd that it worked before. Regards, Harald
