Having had fever all week (stuff swine flu - this was much more serious - man flu), it's fortunately waned sufficiently this evening to take a closer look at my dead board.


I think I've found the fault ...about 25% of the components on the PCB's lower surface appear to have been nuked ....



(surprisingly...there was no inkling of those scorch marks until the board was removed from the recess)



Not looking like such a good buy now! (but to fair the seller did say it would need a new board - but oh no, did I pay much attention - nah, I'm way too cocksure thinking I could likely fix it! ).

I don't suppose anyone has a less knackered motor speed control board that I can buy/fix? ...this one's beyond the pale!
