Paul,
The pushpull 45 amps were built by a Russian guy named Pavel and were sold through a Washington, D.C. area dealership (Deja Vu Audio). These amps used Acrosound TO-330 output transformers (the feedback taps not employed, obviously). The wiring was all point-to-point. In fact, Pavel laid out the amps so exquisitely well that there was almost no wire used in the amp (lead-to-lead connections).
I have one of these amps, though mine uses solid state rectification (most of Pavel's amps employed tube rectification). Some versions used big Chicago brand transformers.
I like the sound of these amps very much. But, my current amps (Audionote Kagekis) are, better to me (at a HUGE price premium).
Deja Vu Audio is an interesting store. They will run almost any speaker with low-powered tube amps which "conventional wisdom" says are way too underpowered. The store sells Quad speakers, and even the 2805 is connected to a fairly small tube amp. The one solid state piece in the store is a Halo JC-1 amp. I asked about it and was told that it is used purely for comparison -- Vu, the proprietor, wanted a decent, high-powered solid state amp for a reasonably fair showdown.
