Build 300B SE tube (valve) amplifier with toroidal transformers

I read somewhere that a bad amplifier can't be made with a 300B tube (valve).
This is my attempt with the standard scheme but with toroidal transformers (Toroidy) and with a slight modification of the scheme. I added the PS anti-noise part (see Aikido SE output stage).
