Default Pete Millett's 829B amp -> monoblocks

I'm not 100% sure about what is going on in this amp. Still I want to build it except in a monoblock version (with a different power supply...I've fallen in love with 3b28's).
What is really throwing me for a loop is the 0A3. I've never really used gas discharge tubes and I don't know what it is doing. If I did a monoblock version would each amp need its own 0A3 in the same spot?

The 0A3 regulates the screen voltage for the input tube. Yes, you'll need one for each amp.

Ok so I basically have to cut the schematic in half and provide each side with its own power supply (and make sure each side has the 0A3 used in the same way as the original schematic)?

Yes. R15 will also have to be duplicated.
