Info as below: Specification as below: Input impedance: 100K ohm Pre amp output impedance: 50K ohm Headphone output impedance: 32-600 ohm S/N ratio: 89dB Frequency response: 20-30K Hz Distortion: <=0.01% Headphone output power: 500mW-250mW Weight: 2.5Kg Component used: WIMA MKP Capacitor. Metal film transistor. High efficiency low leakage R-type transformer. Teflon silver placted internal signal cable. Larger casing better heat dissipation then the 708A. Tube: 6N3 x 1, 6N11 x 2, 6Z4 x 1, 6N1 x 1 Tube rectified power supply, no negative feedback circuitry. A HI-END pre and headphone amplifier at a much lower cost.
