Hope you don't place your power supply sideways or upside down because the '12V voltage regulator' (actually a zener diode and a resistor) can heatup , melt the solder and then the components just fall out of their places. Sometimes a powersupply can be 'repaired' simply by soldering the components back on their place. You could also use a PC AT power supply which is the cheapest alternative with the best performance (better sound quality and no flickering of the TV picture if your Floppy drive start to spin up !)
