Worked on this Watkins Copicat delay unit with Jason at Ampworks, about three years ago.  Supposedly, it was Elvis Costello's;  we had to use a 120 volt to 220 volt converter I found in my basement.  Shit, Jason still has it.  Anyway it was a neat unit, I had to cut new tape for it too.

JOHN BEER  has a ton of information about these on his site.  I have no idea who he is, but I think he's a repairman out in New Zealand.
