The transformers (probably toroidal) are behind the cover plate in the rear.
Single ended class "A" triode amps are quite nice when driving efficient
speakers, such as Klipschorns.  811s, 211s, 845s,etc. are all quite common
for SET amps, mostly due to their low cost an availability. Why not a triode
connected 813?  They are cheap.  The lower power triodes such as 45s, 2A3s,
and WE 300Bs are astronomical in price.  To mee it is the same kind of
economical thinking that drove the multiple sweep tube amps in the sixties
and seventies.
BTW, could we possibly dispense with the disparaging remarks about other
groups?  It is getting quite old, petty and childish. All attributes
commonly assigned to our fraternity by outsiders.  Perhaps a bit of
introspection is in order.

I believe it is what the "audiophools" call a class A transformerless 
design. Lotta tube, little output. Of course it is a perfect match for their

oxygen free wiring which anyone knows you have to have to maintain the 
purity of the sound wave.
