This power supply as noted by the numerous posts and the original video has so many issues that the thermal issue is just the icing on a rather nasty cake! What Dave thought after the first video only Dave knows. I know that I was completely turned off by the terrible rotary knob design and its tracking, the ergonomics of the unit as a whole and the voltage display not showing the exact set voltage plus that nasty spike. The list goes on but surmise to say it was pretty clear to me from the original video that the power supply even before the tear down was not that good, of course that's just my opinion. I guess we will know for sure what Dave was thinking if he keeps the repaired revision as his main bench supply.
You had your conclusion in mind before you ever saw the video, and before you ever knew the specs of this supply. I noticed you have an irrational hatred of it and inflate every criticism to be the worst thing ever, and gloss over every benefit as useless.
Case in point... "terrible rotary design". I don't know what is terrible about it? It is better than the knob on my Agilents. There is nothing wrong with it's tracking. It works great.
Case in point... you say "as noted by many posts has numerous issues". The comments from owners have been overwhelmingly positive.
Case in point... you say "what Dave thought, only he knows". No, we all know what he thought because he told us.
Case in point... you say "pretty clear to me it was not that good".
You have hated this power supply from day one... I have no idea why. But it clearly has very little to do with this power supply itself. The thermal problem IS a deal breaker, but your complaints predated that discovery by a long time.
