Mike, I can't shed any light on the caps but I suspect they won't be any use for coiling. But you're PS catch my attention: >on sunday just gone I blew Steve Bells MMC to heck with my pole pig :-( MMC failures are rare - can you give us more details? are these the caps that a lot of us in the UK are using? What was the voltage? Did it destroy every cap or short out a column.... Alan Sharp (UK)
