Who has built a EL156 SE? I guess it needs feedback due to the nature
of pentode, right?


Plenty of stuff on EL156 if you Google EL156 SE amp.
for example, http://www.single-ended.com/images4/EL156-SRPP-2bs.png

This uses a 6U8A triode pentode in SRPP for fairly high gain for V1
stage to drive the EL156 grid. EL156 is set up for SE Ultralinear mode
with screen tap on the anode winding, probably at 40% of primary
turns.
And yes, it has global NFB.
