was the SMPS moving?

as mentioned above, without a schematic and with every single photo being blurry, its almost impossible to make any comment, even though the idea of a 1.5kW supply for class AB is interesting

95+95*15= 2890KW?

I like you have specced it for single rail operation at one time which is in reality how it will be used.
