Today, I drill some acrylic and heatsink to mount the regulator PCB. What a tiring drilling job! Not too easy to drill a lot of holes on the heatsink, though (not included the wrong holes one!).
Finally, the PCB could be mounted beautifully. The pass transistor mounted on the separate heatsink on the bottom. I just need to wire them to the PCB, add the main transformer, then we can evaluate its performance.
