Re: Pye Black Box
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. Ed |

Re: Pye Black Box
Hi Gents, how about a bar chart of all the long running threads as part of the stats?
