Does anyone know where I could get a power supply (new or used) for a Mac SE? I am hoping to spend less than $50.ANSWER 1: When the power supply went on an SE I was using, it turned out that the problem was a cheap diode that shorted out. The Mac was "flupping" or making a cyclic sound like it was trying to power up, but the current protection was saving it from frying. The fan was also twitching slightly. If these are your symptoms, get a friend who has some electronic expertise to simply replace the diode for a couple of bucks.
ANSWER 2: I've also had two or three SEs with a bad off/on switch. Just short around it and use a power strip, or try and find an equi switch.
