I hope this style of video is better than before.

Two small points
A. Leaving that much exposed wire on the PCB were you soldered wires into the Pot connections, is a real risk of short circuit.
    The purple wire is perfectly done, the other two connections are using too thin wire.
    If you haven't gone back and fixed it, please do, it will make the PSU more reliable.
B. That PCB with 4 diodes on is a mess, use pliers to form the diodes to fit better before installing them.
    Straighten the wires, then bend them 90 degrees over a certain radius to pass thru the PCB.
    Look up the term "component lead forming"

Attached is a cheap lead bending tool I use, official name is "Pro'sKit pk-501D" which may turn up results to suit your location.
The generic term for these is "round nose pliers", also used for things like Jewelry Making.
