Put one to bed today. The second BrianGT amp that I built had nasty DC offset, buzzed and hummed. The current condition of my household is overstocked in terms of audio gear. Let's put it this way, one more 1/4 watt resistor and THE monarch will have my butt.
So this was to be a present for my older son along with Line Array V1. But, I couldn't give him a buzzing turd. I figured it had to be my p!ss poor grounding "scheme".
Following Nuuk's site, I used the 100R/.22uF on chassis ground and the 220pF across the inputs. PERFECT! I had the volume pot cranked all the way and not a sound.
Thanks for a great site NUUK!
