Can anyone help I'm trying to get my macintosh classic II going again.
I've previously tried to get this going with new caps and mosfets but got a thin horizontal line then a blown fuse, varistor, diode, power regulators and eventually found a shorted DC3 on the neck board and dead QC1 transistor.
After replacing all those I powered the mac and got a bong but no CRT power and can see with a thermal camera that QL2 isnt powering.
I'm thinking about replacing QL2, TEA2037 and smaller transistors as a last ditch effort. Any recommendations?
