    I see a big star. We call him Neil Armstrong!

    Yes man, he is on the surface walking.

    I was looking for an explanation why the skies are dark black without a single star.

    Pitch black sky... don't you make this thinking?

    On the moon without atmosphere, there should be millions of them. So funny this shot.

    With all due respect that's a fallacy and not a great analogy in the least...

    I have a 2012 BMW M3 with 75K miles that redlines at 8300 rpm...a V8.  It's not cheap to maintain but it also does not have fundamental issues and falls apart in important places.

    I race a Jeep Cherokee Trackhawk that weighs 5,617lbs.  Boosted motor that I repeatedly beat in the heat at WOT for a mile at a time.  Stop it...rinse and rotate.  I run E85 that I can find at the pump.  Boost is pushed to the max of the catalytic converts.  It's shaped like a brick and I run 185mph in a standing mile and 10.3 sec's in a quarter mile...zero drama for a U.S. based, assembled in Canada and Mexico tub...no drama and I do most the work in my driveway.  Performance w/o drama.  

    I love Italian cars but...no, just no on that analogy.  Sorry...nothing personal...just a topic that I spend a lot of time and energy and reading on.

    Yeah, and the lastest Jeep is a complete ripp off the X5...

    American cars are so bad, that it is difficult for you to realise how bad they are. Only a single US car to win Le Mans ever, not a single US car in Formula One to data. Period. And there is a reason for that.

    Yes, yes you do, because Bugatti isn't an Italian car. It was originally a French car. Now it's a German car.

    It may sound Italian, but I sound heterosexual, so there's that.

    You are actually right, but that was not really the point. 

    Edit:
    The EB110 of the nineties was build in north Italy, not far away from where Lamborghini, Ferrari and Maserati are made.

    I'm thinking if I can do a test load using cement resistors at about .25 amp, that should be fine. 20V/.25 amp equals 80 ohms, 20v X .25A equals 5 watts, this should do https://www.mouser.com/ProductDetail/Vishay-Dale/RE65G80R0C02?qs=sGAEpiMZZMtlubZbdhIBIO9u8NSWRDaQ0Ik%2Fvj6PQ48%3D

    I would put a higher load if you want to load test it. Like at least 0.5A or even 1A.
    Here you can build a simple and flexible load tester.

    that is the bias supply current source and is at at least 700v. best for highest isolation.

    Thanks, Kevin! So, it should not be moved off that Avid heatsink?

    I thought about mounting it downward facing and sticking it to the main amp's heatsink, same as the other sands (I would not be using brackets but mounting them directly on the heatsinks on the amp sides).
