With a 2600V/80-ohm transformer, the 6*1N5408 rectifiers I just posted, a 30uF/2-ohm capacitor, 60Hz mains and 1A constant-current load, it predicts an average for V(C1) of 3260V with ripple between

While that is true, they suffer from the same problem as BNC, in that the bayonet locking force comes from compressing a rubber gasket, which eventually softens and loosens the connector. A better so

Peter's view was that shrew-catching should be an outdoor sport. The cat's view differed. There are actually two, and yes they do. Thanks - I'll print that out and post it to him. No doubt he'd agree
