What about the B+ voltage? Is 179v B+ correct?
Also, do you suggest to use 2 separate regulator per channel? One for the first and second stage (2 x 6922 altogether), and the other regulator for the output stage (2 x 6922)?
What is the current the regulator will see for first and second stage? What about the output stage?
Thanks!
The B+ is correct. Here is the rest of the schematic along with what you posted.

Dear Mike,
Can we have a separate regulator for the first/second stages and output stage?
This means one regulator for the first/second stage and other regulator handle the output stage PER CHANNEL.
I wonder how much the first/second stages required.
thx!
Those are N channel Mosfets being used as current sources and they are keeping the 6922s sections of each tube running consistent with each other.
The 179v source is well regulated also so you don't want to run separate regulators because you basically have separate regulation for each section. Keep in mind that the preamp doesn't draw current as an amplifier would.Those Mosfets are loafing in there.
