ON,
I have built a number of these for customers using the TL404, Dowdy Choke and tube rectifier. I use AC heaters with the 45 and use a 10 or 20 turn hum pot and was able to make the AC noise less than 0.25mV at 60Hz. I don't use any DC regulation but do use a LCLC power supply and usually a 5Y3 rectifier and the LCLC is more like LC---split LC for each channel.
You really have to think about grounding here and the layout.
Thanks,
Gordon
