67 electrolytic capacitors, 68 transistors, refreshed and maintained with attention to details such as main VR replacement to switch disassembly and cleaning, etc. The well-extruded sound with a core is full of appeal that cannot be obtained with modern audio. You can see a feeling of use such as appearance, dullness, small scratches, etc. (Kobayashi Hitoshi)
Maintenance information: 2026.4.17 maintained (67 electrolytic capacitors, 68 transistors, 4 semi-fixed resistors, 6 rear double volumes, 2 spark killers, 2 microphone terminals, DIN terminals, power supply micro switch, fuse, 2 power cushions (ept sealer), 2 meter lamps, main VR replacement. Disassemble and clean 12 rotary switches (power, meter level, BASS, TREBLE, OVER BASS, OVER TREBLE, mode, filter, function 1, function 2, monitor), output level switch, balance VR, microphone mixing VR, headphone VR, impedance select switch, and grease is applied to the contacts. Replace the 20-point caulking fixture on the DIN terminal and RCA terminal with an M3 x 10 screw nut spring washer. Headphone jack and AUX3 jack terminals were cleaned. Each board is re-soldered and flux cleaned.
Disassemble and clean 23 RCA terminals. Power supply high voltage 150V, low voltage 37V adjustment. (Check input/output waveforms, check left and right balance, and conduct comprehensive operation tests)
