So my amp is now silent, but playing beautiful music as I type this. I finally took it to the one electronics guy in my city, who worked on my turntable and NAD 3020 last year. He and I did some troubleshooting together and connected it to an oscilloscope. Wow, was there ever a lot of ripple on this beast. So, instead, of doing the grounded center point with the 100 Ohm resistors, we tweaked the power supply by adding capacitance and resistance and balancing it between the two legs. Each leg now has 10000 uf and .1 Ohm resistance. The voltages levelled out to about positive and negative 3.12 v for the filaments and there is now very little ripple. With my junky sony headphones, there was no hum or buzz at all. With my heresies, the same. Unfortunately, with my D5000, there is some hum, not horrible, but I will add the 120 Ohm resistors in series to mitigate that soon. I will also post a couple pictures and the updated schematic for what we tweaked in the next day or so. Thanks again, everyone, for the help and great advice. Cheers.
