Hi All
Ive just done my first ever DIY build of the Amp6 and eventually got it up and running, Ive still got to add a volume control and a selector control, but the amp itself is working and sounds amazing.
My problem is that when there is no music playing the amp has a constant hum as soon as the music starts the hum goes, at the moment i've only tested with a phone playing mp3s so Im wondering if the poor grounding from the phone is to blame? I will test with a cd player once i get the time.
The amp is mounted in a metal case, do I need to ground the case and if so where from? There a GND hole on C6 that hasn't been used do I connect a wire from that to the case itself? Or is it to do with the DC wiring?
Also there seems to be some hiss on low level pieces is there a way to eliminate this?
Ive attached a pic if that helps?
Thanks
Andy
