Ruby mini-amp finished! (Was: Ruby's volume pot doesn't work)

[TheBigMan]

I uprated all the caps and used an LM386-N4 in my Ruby, so it'll accept upto an 18V input on the DC jack.  It's terrifying how loud it can get through a 2x12" (Celestion G12H30s) and there is a frightening amount of headroom.

Still trying to decide whether to build a Little Gem, a Little Gem Mark 2 or (most likely!) both.
