Nice. I have a QA product myself - a power supply (that is now off their catalog).
I didn't know they had power supply? Can you please share the model name? I wasn't able to find anything, even in their catalog of retired hardware: https://quantasylum.com/collections/retired-hardware .
Yes, I noticed it's not even in their official retired collection. Not sure why. I bought it when QA was just starting, I think. Maybe they're not proud of some early products, or maybe they don't want to mention them as it's a category they don't make products for anymore, so they don't want to be bothered by customers asking for them.
The power supply is a QA300. I was not even able to find any article on it on Google. That's odd. I swear I have one.
(I can take a picture of it if anyone's curious.)
The supply's still working fine. It's a programmable low-noise supply, single channel, with USB connectivity (not powered by USB). I remember there was an issue with early versions, I had mine replaced because it tended to turn off the output by itself for no apparent reason, but they had sent me a replacement unit promptly, without me even having to send mine back, and the new unit's been working fine. The LCD display has oddly developed some burn-in over the years (I left it on for extended periods of time at some point), but otherwise still good.
Don't know, they probably decided that this wasn't a market for them.
