Phone 01703 236363 (Southampton) Not of much use by itself, but they may be adjustable and if they can be connected in series 4 would give you 32V @ 2400 Watts ! I wonder if its possible to inject a 136kHz signal somewhere into its logic and generate 600W directly from the psu? There's a standard £3 delivery charge within the UK for any quantity. Thanks G0ONA for the info. Does anyone have a source for a quantity of electrolytic capacitors for a 28V supply? 10,000 and up. (30,000 is ideal) @ 30 - 40V. Thanks David G0MRF
