Default choke loaded power supply

I am trying to determine the correct choke to use for a power supply. I am using the Hammond 372LX, 520VA, 600v C.T.@690ma, 50VAC, 5V C.T.@6A, 6.3V C.T. @12A. I am trying to power 8 6l6G wired as triodes and 8 6Sl7 for an 8 channel single ended power amp. Any opinions on wether to use the Hammond 193Q; 10H, 500ma, 53ohms, 1000vdc, or the Hammond 193S;1h, 1000ma, 5.75ohms, 1000vdc. There is also the 193R; .3h, 1000ma, 3.5ohms, 1000vdc. Forgive my ignorance, but am I anywhere close? The shematic is basically an expanded version of this Stereo Single-Ended EL34 Hi-Fi Amplifier I thought I would use a solid state rectifier or could I get away with twin 5u4's?
Thanks in advance

Default PS programs!

Have you tried Duncan Amps FREE Power Supply sim program yet?
Duncan Amps who designs & builds amps of all sorts has made available to the public a program that lets you simulate various configurations for tube amp power supply sections. By 'Duncans' generosity you can download this program that will allow you to see right away if your PS configuration will work...or not.
You can explore various parameters......eg. see if you draw too much current from the mains TX......or overload the rectifyer..........or..whatever.
This program will really open your eyes to the various parameters....& lets you know in real-time whats going on!
