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.
