So, Ed, before the thread's closed, what were the main faults, please?

Nick.

Hi Folk, basically damaged lead out wires on the output trans pri, I was fortunate in being able to re-connect them. The give away was the output scope traces being one-sided.
Main trans was a bit of a mystery as there was a 70v low current winding that did nothing.
All traps for the newbies and unwary.
