Hello, Im puzzled. I got a new Beyerdynamic dt770 250ohm for my birthday but I hear a hum on my new headphones with my Crack with the speedball upgrade. I tried a different amp and no problems, plugged my old dt880 600ohm and everything is ok. Any suggestions?

Remeasure your voltages, and also be extra certain that all the 220uF filter capacitors are well soldered.

Thanks, it was my fault when I put a blue velvet pot I screwed up the wiring.
