Default Tubelab SE Using a separate power supply for the MOSFET drains

I'm contemplating using a separate power supply for the mosfet drains in my 45 version of the Tubelab SE. I'm using 2SK3563 mosfets. I have a 230V CT secondary Hammond flat pack transformers (P/N 229B230). It'll do 115V at 100ma or 230V at 50ma.

Is rectifying and smoothing 115V sufficient for a 45 build? Or, put another way, how much drain voltage do I need for the 2SK3563's? The sources are connected to the bias circuit per the schemo.

I'm using the Edcor XPWR-131 power transformer and the rest of the build is per George's parts list.

I'm assuming that I just leave out the jumper between the B+ and DRV B+ pads, and connect the aux power supply to the DRV B+ pad.......
