I've taken a quick look to the linked schematic:

DUH !!, the B+ DC supply voltage is connected directly to the
plate of V5, look not further. The OT has no center tap, it's a
single ended transfomer. Then, both output valve's plates should
be connected in parallel to one end of the OT's primary (usually
the blue wire) and the other end (red wire) to the B+ DC supply.
Either, the schematic has a major error or it was drawn by an
imcompetent dude (lots of 'em around ...)

But the cathodyne phase inverter is correct for a p/p amp. I bet it's a
bad drawing.
