LUXMAN MQ-300 Vacuum Tube Stereo Power Amplifier

This is a single vacuum tube stereo power amplifier with 8W + 8W output, equipped with the TA-300B directly heated triode. It has a simple configuration of a voltage amplification block with two parallel connected 6SN7GTBs and a single 300B power block connected with Luxman's original oil capacitor, and by making the whole unit non-feedback, it achieves a natural and musical tone that makes the most of the characteristics of the 300B rather than numerically high output or high-fidelity performance. It also features a top panel made of 12mm thick aluminum material, large gradient cast iron insulator legs that support the entire chassis, a large-capacity output transformer made of Orient core material with a design reminiscent of the old OY transformer, and a choke coil made of Finemet core material. ■Continuous output: 8W+8W (4, 8, 16Ω)

■Input sensitivity / Input impedance: 490mV (8W) / 240kΩ

■Frequency response: 20Hz to 20kHz (+0.3, -1.5dB), 10Hz to 30kHz (+0.3, -3.0dB)
