Definitely saw that. I was originally looking at ~60 volt rails but going bridged I’d only need 35 volt rails but still 800va like originally planned. A 25x2 - 800VA transformer should do just fine
For those interested, Nelson sent me this email today with regards to max rail voltage for the Stasis FE pcb - as per his design he recommends max rail volts as +/- 60VDC.
Nelson quotes:
"Whatever the transistors are rated at for voltage. I recall the ones I have around here are 120V, so +/-60V is likely the limit. You have to
watch the bias currents as the dissipation on the transistors can get
high. For the big sink Vas parts I wouldn’t want to exceed about 15 mA
at these voltages."

I used them for a DC blocker project, very, very fast. I think my cost was 2 or 3 dollars, the rest was shipping, about 20dollars total for 5 boards.
