The internal looks neat and tidy. On the left you see the mains filter and next to it the rectifier of the mains voltage with two large smoothing capacitors. The electronics are still very traditionally built with axial components on a single-sided PCB with wire bridges. You will search without success for SMD components. Notice that isolation slots are milled into the PCB in many places. The heavier components are fixed with sealant. All in all, this power supply makes a reliable impression. We could not resist performing a few tests on this power supply. Our specimen produced a voltage of 65.263 V without load. Loaded with a current of 5.5 A, the voltage drops to 65.134 V. The voltage drop is thus 129 mV. This corresponds to an output stability of 0.20 %. The figure below compares the hum and noise at no-load (left) and full-load (right). The peak-to-peak value of the noise and ripple at full load is therefore 250 mV.
