This is how I'm thinking of rebuilding it. I think this is the perfect filter, but the voltage drop is a little too much. Most tubes i use, work on higher voltages of 300V, but i guess 250V or 300V isn't much of a difference. The ripple rejection is -67dB. The 760ohm resistor is 2W and the 170ohm resistor 1/2W. Since I'll be using this supply for almost every load, and a typical amplifier will have a varying draw I'd say for the 760ohm resistor 5W and for the 170ohm one 2W would be best.
