Hi All,
I have been woking on the circuit board layout using the DIYLC software (which I think is excellent and easy to use) to design my circuit board. I've had a lot of help and valuable guidance from Trevor and Andy (I cannot thank these members enough) as well as the transformer builds from Ed Dinning. As I couldn't get the spec of the original power and output transformer, I asked Ed if he would build these from those used within the Marshall 18 watt model. With the power transformer, the rectifier power leads were NOT included as a rectifier valve was not used in this circuit. Anyway, this is my first attempt in designing the board with initial modifications recommended by Trevor (many thanks again).
Best Regards

if all else fails...read the instructions!
