Try Russ Andrews
He puts new psu in old Sky boxes and charges �350.
And people buy em..........
Oddly enough, whilst I agree with your sentiment Roger, a replacement PSU in an original Thomson box is almost a necessity. The supplied PSU is awful and the caps degrade over time (you can see them bulging and leaking). This leads, not to a black-and-white failure, but a whole range of problems (e.g. blocking, failing to lock on to a channel) which get worse over time. I replaced all the caps in my failing PSU and, voila, the box was as good as new (which isn't saying a great deal, I'll admit).
