For tube amplifier with parallel connected by 2 pcs 6P1 tubes, the internal resistance of output transformer will be reduced by half, and more control power to speaker, output power increased as double. Because the tubes of power stage is parallel and works under class A status, both to maintain the advantages of a single-ended class A, charm intolerable, bass deep and powerful. The preamplifier used tube 6n8p, whose sound quite lawful, soft mellow, so 6p1’s sound that driven by 6n8p is more charm. The amplifier use tube 5Z4P as pure rectifier, as well as scaffolding by manual, the noise is hardly heard by ear.
