I got my toroidal transformer for my G3YXM 136kHz amp from www.tme.eu as they were the cheapest i could find with sensible carriage costs. They have this: http://www.tme.eu/en/details/55186-p1s2/toroidal-transformers/talema/# > They are not much good above audio frequencies and the turns ratio is > not convenient either. I should accept them and sell them on to > enthusiastic builders. I'd quite like, say, a 500VA 40+40V toroidal for > which I'd happily pay! > Hugh -- Best regards, Chris mailto:chris@chriswilson.tv
