Fully restored! A kit model of a power amplifier using a 50CA10 3-pole output tube and an OY15 type output transformer, composed of circuits and parts conforming to the MQ60 type, which has been evaluated by LUXMAN. The sound of a vacuum tube has a sense of volume that seems to meet expectations, and it gently envelops you. The sound, which doesn't require scale, is particularly unique, and the slight thickness that spreads from below the mid-range makes you feel comfortable. The exterior is dull, rust, abrasions, etc., and there is a feeling of use (Ryo Mizusaki)
Maintenance information: 2024.6.21 Maintained (vacuum tube sockets, block capacitors, electrolytic capacitors, oil capacitors, SP and RCA terminals, semi-fixed VR, fuse holder replacement. Load test (8Ω load 1kHz 24.5W+24.5W), input/output waveform confirmation, impedance switching SW/gain VOL disassembly contact refinement, oxidation and vulcanization prevention grease coating. Input/output waveform confirmation, load test (1 kHz sine wave, 8 ohm load: 28 W+28 W, actual measurement), sound output test)
Accessories: copy of instruction manual
Main specifications: 30W+30W 50CA10 push pull W410 x H160 x D205 mm 13.8 kg
