Hello,

18 V + 18 V = 36 V

Just use two transformers with series secondaries to get close to the "magic" 40 V

Quoting Chris Wilson <[email protected]>:

Hello Stefan and Hugh,



  OK,  thanks  Stefan  and  Hugh, I don't think they had anything over
  about  18V  secondaries.  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:

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
