use a 230:0-40, 0-40Vac dual secondary transformer.
If you plan to use only 8ohm speakers then 2channels will need 300 to 500VA.
if you may use it 4ohm speakers the channels will need 600 to 1000VA.
I don't expect it is properly designed and built to drive 2ohm speakers. I would expect it to drive a 2r0 load for a short while, i.e. until it gets too hot.
With your 240Vac supply you should have about 58 to 59Vdc on each supply rail, but this will vary a lot depending on the demand at the time (day/night).

Hi Andrew
I've ordered a 400VA 42 0 42v toroidal and i'm hoping that will do the trick! You can view the amp here: The schematic is for the Dunlap Clarke 1000 but they both share the same boards. I've replaced the electrolytics with 100volt 22,000uf in the power supply. Pictures by isobarik - Photobucket
Thanks for your input...Brilliant
