Hi,
My problem started after an electrical malfunction occured in my apartment. After the fuses went out in the house i turned it back on, after what all the lights in my room were dimmer then normal and more sophisticated electronical equipment was kinda malfunctioning.. the same was for my amp.
Now i have the current problem fixed i think, but my amp still has this low and strong monotone hum to it..
The led lights flash as normal when turning the amp on, but nothing changes in the tone of the hum when i turn any of the knobs or even the one in the back for simulating a lower wattage amp.
I've tried to do the factory reset, but the hum is still constant.
So I'd really apreaciate if someone of greater experience could maybe help me with pinpointing out the problem before i take it to a techinician.. thank you .
