Yeah that hotsnot thing is really annoying. I find it ok (and it is common practice with many other, and high-end amp manufacturers) for preventing components such as large capacitors being exposed to rattling, but NOT to fix cables. I remember most if not all cables in my Blackmore and Savage - be it ribbon or not - were soldered to solder pads, and not stuck through a via. Thus the hot glueing of the cables.
Actually the PCBs are not mounted upside down, when the amp is placed "normally". But it makes it also virtually impossible to find any bad components or, impossible to measure anything inside, when you have the amp opne and placed upside down with the open chassis facing you. Even more if you don't have a schematic.
Apart from that, I consider the construction as "industry standard" as many others.
As far as the trannies go, years ago I remember reading something about the Savage 120 having more like 80..90 Watts power stage. Maybe the OTs are designed to already distort quite a bit at the rated power...
