Default Korad power supplies

Does anyone have first-hand experience with the Korad power supplies, such as the KA3005D-3S?

The supplies are rather inexpensive. For example, the 2x 0~30 V @ 0~5 A; 1x 5.0 V output version is only about $180. It features digital adjustment of the output voltage/current via a front panel knob, four memories, and USB connection.

EEVBlog has a tear-down review video of the single output version. I believe the single output is $120... You certainly get your money's worth it seems like. Granted, the build quality could be better, the boards could be washed, etc. but for $120... Not bad.

Has anyone here tried any of these supplies? I'm curious about what the output impedance is and how much residual ripple is on the output.

Modulus-86: Composite amp achieving 0.00018 % THD. Damn Good 300B, Novar Spud, 21st Century Maida Reg., Filament Reg., etc.
