Thanks for your replys.
Melchead, did you need to add the diodes and the filter Cap to your transformer, because there is no diodes in the original Diagram for the circuit? Could you post a diagram of your layout/ the components you used (I am in singapore so 230vac is fine for me)
According to the original circuit I should be getting 25vac, 2 amp out of the Transformer (obviously I will only get 15vac, 2amp). Could this be correct, or am I missing something on the diagram?
I have reattached the original diagram for ease of viewing.
