RE: 4P1L preamp DIY

I built this line stage recently and really like it. I use it between my SACD player/DAC and my S&B 102 TVC. It only has 6 to 7 db of gain with the Lundahl 4.5:1 step down so it works nicely with my system. I used the schematic posted by Kevin Carter on his forum and I used his filament regulator and shunt regulator boards. The signal path is pretty simple really. It requires Rod Colemans regulator boards. I'm not much for adjectives but the sound is larger and deeper and more dynamic.
