My 2nd DMD, i got a white water a few weeks back too..

I imagine the hi-voltage lines (although only 100v) will be attracting dust and junk to it, much like HV (25kv does in TV's).

MM,

Sounds like you may be onto a holy grail of pins...Strikes and Spares (NIB), South Park and WW????  Any Fathoms or Spirits hiding out back!?

Still need to drop those plastics off to you at some stage.  I should be at Marks on Sat or will give them to you at Meet.
