YaQin MS-110B KT88 push-pull tube amplifier. Power tubes use the latest improved KT88-98 and strong output push-pull circuit. Preamplifier part is as “SRPP” circui. T and excellent “long tail” type inverter circuit. So that a wider frequency response and better sound quality. Audio output transformer dedicated silicon steel imported from Japan (0.35mm thick) and oxygen-free copper wire and special high-strength multi-layer winding process grouping production (divided into 15 layers), so that the machine wide frequency response, ensuring. High the machine,, the low-frequency sounds good, transparent and powerful. The machine adopts well-know brand dedicated audio BC capacitors and also Philipps (MKP) nonpolar capacitor. High quality gold-plated resistor. The main channel using a dedicated sound Japan (ALPS) volume motor potentiometer with quiet background music, noise low, no sound pollution and durable. High voltage power supply for the automatic delay control, can effectively extend tubes life. Switch between ultra-linear (UL) and three poles (TR) connection mode, to meet different user needs. Function with remote control and high quality headphone output. Output Power: 50W + 50W (6ohm). Harmonic distortion:? 1.0% (1kHz). Frequency response: 10Hz – 50kHz (-2dB). Signal to noise ratio:? 85dB (A). Input Sensitivity:? 0.3V (1kHz). Load Impedance: 4? – 8? Shuguang 12AU7 × 2, 12AT7 × 2. Voltage input: switch between 110/120v and 220/230v or 240v, 110/120 or 240 need 5days processing time. Neight weight: 21.5kg.
