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.
