That's what I get for using the word "final"
I just uploaded an edit on the above post with the requested clarifications, and also made a note that you only need ONE of the EFB(tm) cathode regulators (upshot -- you need to use a matched-quad of tubes because that's the adjustment granularity). As for wiring up the tubes wrong -- I always find it handy to have a copy of the tube's data sheet handy when building. Note in my schematic update, I left off the pins used for the tube heaters (because I never draw the heaters in my schematics unless some exotic configuration is necessary).
As for bias, as noted on the schematic, you want to measure the voltage drop across the 10 ohm 2W 1% resistor that sits between the 6V6 cathodes and the LM337 output terminal. The bias will be adjusted properly when you have a 1.2V drop across that resistor, which represents 120mA of current (30mA per 6V6 of combined plate and screen current). This should be at around +22V on the 6V6 cathodes (which is a bias of -22V, because the grid is pulled down to ground).
