The TB-100 features carefully selected, quad-matched ECC82 (12AU7) tubes, optimized specifically for this model. Using in-house tools, performance variations during operation are minimized to within 1% (0.1dB), ensuring peak performance. Each channel is equipped with an inner tube for voltage amplification and an outer tube for output buffering, delivering a rich, transparent sound quality. Moreover, the amplifier employs straightforward two-stage amplification circuit paired with low-impedance cathode follower output stages to provide a pure and dynamic audio experience.
