One Caddock resister direct from XLR to tube, a fabulous design.
There is a reason Atma-Sphere amps sound so wonderful... many are made with extra love for their owners.
I miss the 336, it was a beast, best by the Rowland M501. The Atma M-60 preferred to both. I am an OTL guy...
Looks like it is in motion

One of my favorite amp designs, it is brilliant
this was my inspiration for shoebox amp

I typically buy 3 of each amp chassis before I begin working on them, I will build amps in stages, compare and make notes. The first build usuallly proof of concept, then refine step by step, linearly until all 3 are the same or close.
Always modeling circuits, building and comparing...
