My issue is that bigger is very often better. I brought NP into this so I wouldn't once again be denigrated as a complete poser or maverick... As to what type of trannys are best between box and toroidal I don't know. All I "know" is that either one would almost certainly sound better to me if they were bigger, using a smaller gauge numbered, larger diameter wire for their windings. By this I mean either a bigger toroid than a smaller toroid or a bigger box than a smaller box, not comparing the two. Tweaker

I brought NP into this so I wouldn't once again be denigrated as a complete poser or maverick...Whether you succeeded is a different matter. You'd have earned slightly more respect, at least from me, if you'd read his piece with more care.
In passing, though Beautox has probably forgotten more about amplifier PSU design than you or I are ever likely to know, my understanding is that NP used an electrolytic in a single-ended SS design. What else could one use there? (Apologies if I've got that wrong.)
Whatever, esp if using good quality caps (slit foils?), SE designs can sound very fine indeed. Tracing the current loops suggests why.
My flavour of the moment is a chip amp without any caps in the signal "path" and only 2 x 1500uF in the PSU. It need a biggish transformer to work well and, it being a toroid, care taken to get a clean mains.
There's a mad fellow in NZ who sells products that bring chip amps up several notches. Maybe a little low on power for some but I've never heard such a sweet, clear sound from an amp. (I'm not familiar with SE tube designs.)
IOW, though "bigger is better" can work very well, it's not an absolute principle.

I see no distortion of NP's view on the subject of bigger is better in power supplies in the excerpt I posted. His article is titled: Manufacturers Report - "The Importance of the Power Supply" - May, 1997 T456

Now, on a serious tip;
I tend to agree on the biggest, most robust power supply in any power amp.
Is your chip in a socket?
"...using a smaller gauge larger diameter wire..."
That's something I haven't seen. Must be something created by a marketing department.
I edited it to say smaller gauge numbered. In actual fact I don't think that even you are too stupid to not have known what I meant. What am I marketing, preytell? Just another inane comment that has nothing to do with anything of substance or possible use.
Tweaker,
Only you know what you meant. All I can do is read what you wrote, so either write what you mean or quit whining about it when you don't.
"Just another inane comment that has nothing to do with anything of substance or possible use."
ROFL!!! My sincere apology for stepping on your turf.
