Though my main power supply, which I picked up a few years ago on eBay (new), is a BK Precision 1672 triple-output monstrosity, I recently got another one. Since it hasn't entered the mess of wires that is my workbench, it's easier to post photos of this one. I got it because it was smaller, though not lighter, and because it had an output voltage up to 60V. I can attain 60V with my 1672, but I wanted a single supply (technically dual) that could do the same.
I got it from a fairly local distributor known for their dealings with educational institutions, Electronix Express. What I bought was their part number "6003LK-2", which is advertised as a RSR Electronics product (Their parent company), but actually ended up being a Vizatek product. No matter the details, though.
I paid $145 for it and think I'll end up being happy with it; however, I wish the panel meters were more accurate.
In the picture below, I am measuring the current and voltage with my Fluke 117 and 85V respectively. The load ended up being the closest thing nearby when I decided to take a picture, a random 2W multi-turn potentiometer. I plan to someday build my own linear supply with readout accuracy down to 1mV, which I'll likely be very very anal about, but I'm not quite satisfied with what I see here. The current measurement is off quite a bit at low values, which is a problem in my book.
It has the most enormous torroidal transformer I've ever seen inside of it.
It also has a fan that seems to be on constantly, which is annoying. The same goes for my 1672.
Also, though the BK Precision 1672 also only shows current and voltage with 0.01 units accuracy, I found the panel meters matched my DMMs very closely in comparison.
I'd still buy another if I needed it, or maybe something similar. You can do pretty well in this price range.
I'm repairing some BK Precision 1630 DC power supplies from the early 90's for my former electronics instructor at my former High School and they're still working just fine despite heavy abuse. The main issue was that the cheap plastic front panel seems to have leeched its plasticizer, which made it brittle and caused it to crack. I imagine that product had a similar cost when it was new.
