All of Fjord Audio's amplifiers only a complete Class A with the highest level of sound satisfaction.
Feedback is a factor that interferes with natural sound. It's not easy with a vacuum tube, but The Zero Feedback circuit has been completed.
In vacuum tube amplifiers, we have completed a unique Direct Full Difference vacuum tube circuit.
All of Fjord's products pay special attention to the design of the power supply. We intentionally applied a classic filter, By focusing on minimizing noise and providing sufficient power, it provides sufficient gain for actual sound.
Vacuum tube amplifiers that maintain high pressure and temperature should not use general PCBs. Fjord Audio has secured quality in terms of lifespan and heat generation through the PCB by applying military-standard copper plate thickness of 105㎛.
We use a unique UTS mechanism structure to reduce harmonic noise that may occur in vacuum tubes.
P150 always checks the bias of the output tube to maintain the best condition and operates an automatic protection protection circuit in the event of overvoltage.
All amplifiers basically employ Standby Power and Mute circuits.
Uses specially selected Fjord vacuum tubes, Quality was secured through pair matching and aging in the production process.
Through technical partnership with a transformer specialist company recognized as one of the highest in the world. We have completed a high-quality, high-performance transformer.
Designed as an independent program through collaboration with an Attenuator specialist company, It is an etunator with precise performance and quality, and uses resistance.
Applying South Korea’s R&D and sound tuning, incorporating China’s manufacturing infrastructure
