All of this stayed on the back burner until Kevin Carter of K&K Audio told me about building an amplifier that used a pair of PP 2A3 driver tubes instead of 5687/7044/7119's.

In my opinion the 2A3 and 300B aren't that far apart, the 300B has a very laid back lush sound loke if the music is thick. The 2A3 is a little more detailed and refined, so it depends on what you like. Also the 2A3 is about 3 wpc and the 300B is around 8 wpc.
Inside the amplifier at the tube sockets are a pair of ferrite core transformers, which provide isolation from the power oscillator and drive the 2A3 heaters. The transformers are wound 2:1 so 5V in is 2.5 volts out. The high frequency is calibrated to exactly 2.5V at the tube socket with the tubes operating. The chassis design is shared with the Triode Lab 2A3 EVO SET integrated amplifier, as well as the upcoming Triode Lab EL84TT EVO integrated amplifier, and is nicely laid out for a visual treat. Just seeing the Triode Lab 45 EVO integrated amplifier sitting in my living / listening room made lust bumps pop up all over my body!
