Power Supply Refactoring - part 3

Bit by bit the work is advancing. I have finally defined the schematic diagram from the entire power supply circuit. It includes also the PIC based fan control.

The AC input wiring have also been completed, with the front panel dual pole switch connected:

All the pots and buttons are now available on the front panel:

Also drilled the heatsink to support the power transistors and bridge rectifier:

Also finished the back panel with the power connector and fuse holder:

The next step is to layout the circuit in breadboard and test its main elements against a DC input. At the end I should be able to check if the expected results are obtained.
