For sure. Earl is a great guy and has been very helpful consulting with my build. Here are a couple of pics, even one with him. He used to live in PA, but moved to Scottsdale AZ many years ago. I moved to Mesa AZ about 6 years ago, we are only about 30 min apart.

By coincidence I bought this exact power supply plus the very similar +450V DC fixed voltage model. Actually, they arrived today, too, and I tested them before leaving work.
BAD NEWS: both are defective. 1st one (adjustable) is squealing badly from the transformer and the output is sh*t. The 2nd is pulling down the input power source and getting hot with no load.
I'm emailing the seller right now.

I got this response from the seller:
"these modules are designed mainly for charging capacity.
yes the sound is not very low because of the big current. it should be no big problem as long as the module is working right. and yes its output is not very accurate as it is used for charging capacity.
however it sounds strange How the second module acts."
I'm not sure but I wonder if the first one isn't rectified/smoothed on the output, hence why it's so small. Regardless, the screeching noise is terrible.
I ordered the same one tested by the guy in the YouTube video (posted 1st page of this thread) so when it gets here I'll check it out.
