KONDO AUDIO NOTE JAPAN DEPARTURE POWER AMPLIFIER


And more news for Kondo Audio Note Japan fans. Departure EL34 based tube power amplifier incorporates many of the Kondo’s unique features and hand made parts... A new, highly refined and carefully tested push-pull circuit with was developed in order to achieve a high level of balance between the dynamic and delicate tone of EL34 pentode tube. Audio Note Japan Departure tube amplifier was  to potently drive modern speakers. For this the multipliers and current values ​​in various parts of the circuit were highly optimized.

Characteristics

The first driver stage is a direct connection circuit, and a new generation pure silver foil capacitor with anti-vibration propensities is used for coupling with the output stage. Moreover, the low impedance of the whole circuit is adopted that consequently deliver direct/intimate sound.


The output stage use its own CCB (constant current bias) circuit. This prevents music signal to be affected by the usual bias adjustment, and consequently a pure signal transmission is enabled.

Optimized wiring

All the signal paths are optimized and minimized and hand wired. SSW (silk silver wire) is used for internal wiring, and Ls-41 is used for shielded wire.

Power supply

Departure amplifier is equipped with a power transformer that implements a newly designed large inner core. The power circuit consists of a choke and high-performing capacitor bank.

Decoupling capacitors have been placed independently on each side, and carefully designed to minimize signal loops.

High quality parts
  • A new-generation of pure silver foil capacitors with anti-vibration qualities are used in the driver stage.
  • Pure silver SSW WIRES (silk silver wire), Ls-41 (shield wire), and carefully selected CR parts are placed effectively.
