Someone has sent me a picture of their Elston board and it looks exactly
like mine with B411 transistors.
However I noticed that there are no signs of heat around diodes CR102 and
CR409, whereas mine have distinct signs of heat on the PCB. It's possible
that the other board has had lighter use, but maybe the heat marks on mine
indicate a problem? Should I be concerned as they do involve the flyback
transformer?
Thanks
