Hi!
I'm assisting my friend to source some parts for his project and he is working on a pretty interesting amplifier that is a 300B push pull amplifier with 300B for driver and input stage as well.
He is thinking about to use the Lundhal 1:1+1 input transformer => 2 x 300B PP => 1+1: 2+2 IT => 2 x 300B PP => 1+1:1+1 IT => 2 x 300B PP => output transformer with 6.6K primary.
Don't you guys think it has adequate gain to drive the output??

Gain depends on your speakers and preamp output. My only comment is an input transformer prefers very high impedance on its secondary; a 300B is anything but. As wild as the design may sound with all those 300's, I think you'll be better off with a first stage having less capacitance at the grid.
