Re: Power failed, R60 extreme hot :(
Hi.
Before replace the tip2955 i got around 7v between the legs at r62.
After replace, i get the same, so its another problem. I get around 20v in at 7812, and 12v out, so it seems to be right.
I get only 6v in at 7805 by the way, and only 3v out, could it be a faulty 7805?

It also seems like I only have around 4v out of the 7805. I wonder if it could be the tip that failed? Around the area, with the Regulators (next to the...
