Cutting edge components and construction
Dual Nutube 6P1 Vacuum Tubes
Manufactured by KORG and Noritake, the 6th Gen Nutube operates exactly as a conventional triode vacuum tube and creates the same characteristic rich overtones that are sought after in triode tubes. At the same time, Nutube achieves substantial power savings, miniaturization, and quality improvements when compared with many conventional vacuum tubes. Voltage amplification is achieved with the Nutube, which results in a captivating and distinctive vacuum tube sound, all while maintaining exceptional linearity.
Efficient Pure Power Supply
The PB5 utilizes six batteries to establish a robust power supply system. The Nutubes are powered by 2 batteries while the other 4 batteries function as the power supply for the secondary amplifier. With an efficient and pure power supply, you will experience immersive and crystal-clear sound.
24 Position, 4 Section Stepped Attenuator
Extremely diminutive 24 position, 4 section stepped attenuator. Optimal analog volume control enhances the ability to showcase the distinct analog characteristics of our vacuum tube amplifier. Channel imbalance is within a range of less than +/-0.1dB. When adjusting the volume, the noise floor is simultaneously attenuated.
2-Step Suspension & Cathode Input
The two-step suspension absorbs vibration mechanically and minimizes microphonic effect. The cathode input reduces the impedance, resulting in reduced signal interference from external sources.
Cutting Edge Components for Ultimate Analog Sound
24 position 4 section stepped attenuator with a channel tolerance of less than +/-0.1dB.
Texas Instruments classic OPAMP OPA827, known for its exceptional performance and rich analog characteristics.
Low VCEsat (BISS) dual transistors with a high output current of up to 2 amps.
iBasso custom film capacitors contribute to the natural analog magic.
