This is another lab power supply i made from old computer power supply. It's double pole, adjustable 2.4v-27.5V, between both poles there is 55V. It's easy to make this, you need to desolder all output components, leave everything around main ic and solder couple of new parts( resistors, capacitors, potentiometer).

Step 1: The Circuit
Don't watch at output section. Only use everything that is around the main ic.
