    Little DOT MK III Mods??

    Couple of suggestions: 1. email Sword Yang (little_dot at vip163.com) if you still need help. He's pretty responsive. 2. Take this opportunity to drop in a new and better quality pot.

    Little DOT MK III Mods??

    ------ Hey Critical Bill, your post has been immensely helpful! I did notice something however, that I hope you can help address. The 0.047uF (47nF) yellow Carli caps in the photos appear to be safety line caps marked and rated as X2. I am not by any means an expert, but they seem to be...
