This is the aux power supply.
When power on, the input power inceases 70 between 100 VAC first the aux power supply started, the Volt/Amper display lighting up.
If the input voltage continue increases to 150 VAC the main supply wake up.
Between the main output ( Red-Black ) jack I measured cca. 20 Ohm.
Maybe this is a short circuit?
Now the aux supply can't start- try per second...
The support it has helped me so far...( sen to me the aux ps picture)
It stopped a few days ago.
I waiting...
