Azzenanù 22

Azzenanù 22 • Lower-Wattage Extremism

The Azzenanù 22 represents analog extremism applied to lower wattages. This One-Off architecture was conceived on the Atelier workbench for a single purpose: allowing the true, noble sag of the output transformer and the biological dynamics of touch to breathe, erasing every single milligram of industrial acoustic mud at its source.

Beneath the white chassis lies a 3D Point-to-Point air-wired layout, structured by rejecting the compromises of printed circuit boards and employing an elite component selection and circuit topology unprecedented in the guitar amplification realm:

• Rock-Solid Power and Filtering: The energetic heart is governed by a GZ34 rectifier tube, combined with a dual-choke (double filter inductor) system and a monumental reservoir of MKP polypropylene capacitors. This synergy collapses overall ESR to zero, ensuring an unyielding reserve of instantaneous current and stable plate voltage. The power supply remains rock-solid, allowing the circuit to express only the noble magnetic compression of the tube.

• Flow Management and Cathode Bootstrap Tone Stack: The equalization section rejects the limits and fragility of standard commercial designs. By introducing an esoteric Cathode Bootstrap configuration with a recovery stage, the layout safeguards the vacuum tube by isolating the potential, preventing the circuit from reaching the maximum cathode-to-filament voltage limit (V_kf). This elite engineering choice preserves surgical control efficiency while ensuring absolute long-term system reliability.

• Linearity and Biological Dynamics: The output stage operates in cathode bias (automatic bias), perfectly following the elastic, dynamic interaction between the valve and the speaker's impedance curve. The transparent effects loop is engineered to state-of-the-art standards using high-voltage LND150 MOSFETs, fully preserving the integrity of the analog path.

• The Synergy of Passive Components: The signal path and critical nodes utilize a millimetrically calculated acoustic blend: the harmonic smoothness of carbon composition resistors merges with the surgical precision and ultra-low thermal noise of high-end Vishay components.

The white front panel offers absolute control over this electron kinematics, allowing the handling of voicings (Raw, Spike, Clip, Fat, Modern, Flash, Clear) without ever altering the total micro-dynamics. 

A three-dimensional, esoteric sonic experience born for those who seek the soul beyond the signal.

INTEGRATED SPECIFICATIONS 

• Thermionic Heart and Real Power: The architecture is driven by a power pair of 2 EL34s in the output stage, supported by 4 12AX7s dedicated to preamplification and voicing management. The system's engineering precision delivers a maximum measured power of 19 Watts undistorted on the Clean channel, reaching 22 Real Watts in full dynamic output.

• Rock-Solid Power and Filtering: The energetic heart is governed by a GZ34 rectifier tube, combined with a dual-choke (double filter inductor) system and a monumental reservoir of MKP polypropylene capacitors. This synergy collapses overall ESR to zero, ensuring an unyielding reserve of instantaneous current and stable plate voltage.

• Flow Management, Bootstrap, and Master Control: The equalization section introduces an esoteric Cathode Bootstrap configuration with a recovery stage to safeguard the vacuum tube by isolating the potential, preventing the circuit from reaching the maximum cathode-to-filament voltage limit (V_kf). Volume management is driven by a Post-Inverter Master Volume (PPIMV), the only solution capable of preserving saturation and phase dynamic integrity before the output stage.

• Linearity, Effects Loop, and Passive Components: The output stage operates in cathode bias (automatic bias), perfectly following the elastic, dynamic interaction between the valve and the speaker's impedance curve. The transparent Serial Effects Loop is engineered to state-of-the-art standards using high-voltage LND150 MOSFETs, fully preserving the integrity of the analog path. The circuit utilizes a calculated acoustic blend of harmonic carbon composition resistors and high-end, low-thermal-noise Vishay components.
