Item arrived with a piece of the plexiglass broken, fixed with some superglue. The adjustable power supply showed some odd behaviour, only a small portion of the adjustment range of the potentiometer was used. By replacing the two (positive and negative) 2kOhm resistors with 5k1 resistors the adjusting range is now okay. Mains cable was very short, now replaced with a longer one with the proper mains-plug. Measured the output voltages (unloaded) these are okay. Overall, very nice unit, but needs some work.
