A guy connected 16V AC brick instead of 12V DC brick.
There are some two tiny components of package similar to SOP, just have like 2x4 mm. Probably protection devices for this purpose, they do not have continuity with voltage applied. One is labeled RADRRR and has 5 legs. The other one is 6-leg 564Z and this should probably pass the voltage as there is +12 V coming in and output should go through filtration capacitor into AX3108 PWM step-down controller, but has 0,13 V on output (thus 0,13 V on capacitor and PWM). Any idea what this is?
