I recently came across this amplifier and was wondering from a design perspective what advantages it might have. It's essentially like many single ended 300B's we have all seen here, with basically a full dual-mono power layout even using 2 rectifier tubes. It's also got a small change here of driving the 6SN7's in parallel by using both triodes at each stage. This amplifier is also ridiculously $$$ expensive, but I'm a bit curious about the potential of trying this as a DIY project. Would similar values of resistor and capacitance still work with this parallel drive design? I'm a bit fuzzy on what the advantage would be but I'm guessing maybe higher current?
