There certainly are other hidden flaws in this model, to enumerate a few:
- a radiator too small in the first version (mine is already the version with a bigger radiator)
- faulty internal wiring of the GND between channels 2 and 3 (this is mostly noticeable at high current)
- the faulty twisting of force and sense wires
- binding posts out of tolerance
- noisy fan
maybe a couple of software bugs, too, to name only a few.
Though, given its price (~$600 new, in 2015), the fact that I never needed to use it at full power, and that it was possible to unlock the mV/mA resolution together with all the other SCPI and software features made it a decent power supply.
Here, in EU, the choice of second hand lab instruments is very limited when compared with what is available on ebay USA.
