Hi Malabar.Your transformer seems to be open, maybe a small hidden fuse in the winding.With the amp disconnected from mains (double check that) measure resistance across all windings.Draw a simple schematic showing them and the resistance measurements.Thanks.PD: I seem to recall that somebody had a problem similar to yours, slit open the outer insulation paper and found, skin-deep, an open thermal fuse, but i'm not quite sure. Measure yours and we'll see.In the worst case, you can find a new replacement transformer at a reasonable price.
Even before slitting anything, what are the winding resistance measurements?

I did find an authorized service center I can buy one at - for $40. Which seems about twice what a chinese low-current xformer SHOULD cost but I'll gladly pay if I can get this thing rockin
Ok, those are consistent measurements. In an SS transformer, the thinnest wires are the primary ones, and on a very severe overload can act as fuses.Of course the transformer gets open and unusable.Even if the secondary didn't actually melt (good or your home would be in fire) it overheated so much as to melt plastic *and* compromise the enamel's integrity, so even if it had continuity on the primary, I would not use it.If yiu can get a direct replacement for $40, good.If not, I think somebody had the same problem here and posted some supplier.There is also a member of this forum, I just don't remember his name now, who usually has various transformer, good quality, interesting price.Search for it or maybe somebody with his brain less damaged than mine does remember better.I seem to remember that your amp had a chipamp output.Good because it simplifies service.
