Perfect tone and breakup

The breakup sounds really nice.

Better output, smoother breakup, cleaner sound

The sound is pure crap--theoretically this places the amp into Class D operation, loads down the output transformer with hysteresis coil saturation and kills any Fourier Scale harmonics to the point of sounding Class A at a operation curve/quiescent current ratio in which you can kiss your odd order harmonics goodbye and when pushed hard even the 7581 A tubes which can handle upwards of 550vDC on the plates, break up early and sound like a Fuzz Pedal due to output transformer coil saturation.
