Well I have bought what I think are the right parts
For Info here are the part numbers and the suppliers
Just awaiting the soldering Iron from ebay to come in the post
I tried to buy the best parts available (even overspeccing some resistors - yeah - like I know what that means)...
Unfortunately I donl;t know whther I bought the right type of Swoter transformer - I think I should have bought the PCB pin one - but this is the one I am getting... so be it..)
