HiFi Class A Power Amplifier Tube Power Amp Output High-End Amp For Home Uses P-69 Features: – CNC aviation-grade aluminum body. All aluminum carved, high-end brushed to make the body more beautiful. Bright and lasting as new. Surface oxidation process – 130W ring-shaped transformer. It is made of imported iron core and imported pure oxygen-free copper wire, so that the power supply can transmit stable power continuously – Pure copper gold-plating terminal – Customized components – Output protection system – High dynamic amplification – RCA signal input – Cost-effective with better sound quality – Balanced, high-end. Pure sound and strong thrust – Low-frequency powerful, sufficient flexibility, dive deep – High IF density, full and thick sound – Delicate high-frequency sound – Meet the needs of 95% of HiFi users – Can promote 90% of bookshelf landing symphony performance – Pure Class A 10W output, actual driving force 100W per channel – Golden ratio of the chassis, built-in powerful radiator, to better heat dissipation for Class A circuits. There is no limit to indoor placement – Beautiful and high-end appearance – Carefully selected parts to pursue better sound quality – RCA and speaker terminals are all pure copper gold plated to ensure the transmission of sound quality – Exquisite workmanship conforms to the precise sound field details of the pure Class A amplifier circuit – Left and right channel mirror symmetry maintains good separation, and the small signal amplification part is far from the power supply and transformer. The difference between the principle and characteristics of the digital circuit, the corresponding multi-level CRC filter combination, the original imported capacitor, significantly improved SNR, and the large dynamic performance retains the original toughness Specifications: – Audio input: RCA input x 1 group – Audio output: Dual channel class A amplifier output – Total power consumption: 65W; Max. 130W – Input impedance: 47K – Output impedance: 4-8? – Output power Class A: 10W X2 – Equivalent to Class A and B: 50W x 2 – SNR: >115dB – THD. Note: Power supply is not included in the package. Usually it cost about 35USD-50USD. Thanks for your understanding. If you receive defective item, please kindly notify us within 14 days.
