GZ34S is 5AR4 octal base rectifier diode. It provides strong current output. Suitable for all Hi-Fi and Guitar amplifiers.

All materials used in tube production undergo a meticulous cleaning process such as ultrasonic cleaning, annealing in protective atmosphere and reactive rinsing. The assembly process is carried out by a combination of meticulous manual operations and state-of-the-art production procesess.

All vacuum tubes go through an extended burn-in period to ensure superior stability. A rigorous final test for every important parameter. In particular, the parameters for flawless tube functioning include insulation characteristics, vacuum level, cathode emission efficiency, filament voltage, plate currents, and microphonics. The quality control process includes several thousand hours of reliability testing on samples of tubes.
