Hans,
I just went back and checked. The clicks were there as far back as 004 (Rev1 PCB). However they didn't become nearly as obvious until ver 012 when the volume control was fixed. But the max gain prior to ver 12 was much lower. So I believe that the clicks have been there all along, but didn't become really bad in ver 12 (or 11, which I didn't test.) That was when you could really crank up the volume.?
