From the condenser to the socket volume, 56 deteriorated parts have been replaced, the switch volume has been completely dismantled, the contacts have been repolished, etc., and it has been completely overhauled! *The output tube has been replaced from 8045G to KT88. Furthermore, the speaker terminals have been replaced to improve convenience. It makes an overwhelming sound even when compared to the company's A series and MQ series (Daiki Goto)
Maintenance information: 2026.1.23 maintained (vacuum tube (6240G), vacuum tube socket ✕ 12, capacitor ✕ 18, resistor ✕ 2, RCA terminal, semi-fixed VR, spark killer ✕ 4, SP terminal, diode ✕ 16, micro SW ✕ 4, fuse, power cord replacement. The board was re-soldered and the input gain VR disassembled and cleaned. Load test (at 1kHz, 8Ω load: 60W for both). Check input/output waveforms and perform sound output checks. SW/VOL disassembly contacts are re-polished and grease is applied to prevent oxidation and sulfidation. Input/output waveform confirmation, load test (1 kHz sine wave, 8 ohm load: 60W+60W, OK), sound output test.)
