ABSTRACT:
A high-power, high-fidelity tube amplifier which includes a plurality of output tubes connected in parallel with individual current sinks and a plurality of parasitic suppression components. Each current sink is electrically coupled to its corresponding output tube such that the output impedance of the current sink decreases as the grid current of the corresponding output tube increases.
