Thanks for you input. Seems like we exchanged posts regarding driver stage harshness in the amity design. You are probably right about sticking to the less complicated scheme of a single lc. I was looking for a little less ripple. On my SE 300b I had to use two stages to get the hum down to an accepatble level (less than 1mv) - I am using a pentode driver, which has poor ripple rejection. On my pp2a3 I am using a knockoff of the GE 97fxxx series motor run for the WE cap and also as the cap that essentially bypasses the final ps cap. What type of caps did you use in your PS? Did you use the shunt regulator tube on the driver stage?
