The disposal price has been reduced. Member discounts are not applicable. 2024/11/5 sales price 448,000 yen ※The hood is out of stock. 2019 restored model! The original model 8 is now in stock! This is a famous gem that has both thickness and sex appeal while making a quick sound. There is no boomy sound, which is a drawback of vacuum tube amplifiers, and it is a vintage sound that is still popular today due to its good tone and good balance. There are stains and scuffs on the exterior (Sasaki Shota)
Maintenance information: 2019.9.21 Maintained (replaced due to defective block capacitors. Electrolytic capacitors were replaced with SPRAGUE ones. SP terminal deterioration replacement. Foot leg damage and deterioration replacement. BIAS reconditioned vacuum tube socket and RCA jack caulk repair. Other operations have been checked)
Accessories: none

The disposal price has been reduced. Member prices are not applicable. 2024/9/12 sales price 298,000 yen Maintained! This model was the predecessor of the Redeemer WX-1P tubular power amplifier. The 6550 push-pull 5-pole connection makes a lot of noise and plays music vividly. The heater and B power supply are designed to be switched with a standby/operation switch. Bias adjustment with a meter is also easy to use, and you can adjust it yourself even when the vacuum tube is replaced (Yasuhito Koshihama)
Maintenance information: 2024.11.16 Maintained (output tube replaced → running test performed.) 2024.9.12 Maintained (6 block capacitors replaced due to electrolyte condenser liquid leakage, mute switch replacement, bias switch cleaning, vacuum tube pin cleaning, bias and output sound checked. Output approx. 65W in AC 100V environment (5 connections)
Accessories: power cable, circuit diagram, English manual, catalog

The disposal price has been reduced! Member prices are not applicable. 2024/11/9 sales price 598,000 yen Maintained in July 2019! A tubular mono power amplifier that makes you hear a profound, Macintosh sound. The highly transparent sound was restored through an overhaul. You can enjoy the relaxed and calm sound unique to vintage McKinn. ※The left and right specifications are different. Some lettering is peeled off on the exterior, and there are corrosion marks, scratches, rust, etc. on the chassis. Serial 5698/553 (Yonejima Satoshi)
Maintenance information: 2019.7.18 Maintained (volume disassembly cleaning repair. Vacuum tube 6550 deteriorated and replaced with 2 pairs x 2. Replace 2 vacuum tubes with 5R4 → 5U4 original ones x 2. Vacuum tube socket and RCA jack re-caulking repair. 5689 side block capacitor 35/80/15 μF replacement)
Accessories: No accessories
Main specifications: 60W load 4Ω/8Ω/16Ω frequency characteristics 20 to 30,000 Hz W356 × H203 × D254 mm 20.7 kg
Internal and external maintenance has been completed in 2020, such as replacing the coupling condenser with an oil condenser, replacing the banana-compatible SP terminal, and replacing the vacuum tube (50CA10)! This model is based on the concept of making sounds even more straightforward than the MQ60. The warmth of the tone and the indescribable luster sound are truly lackstones. The exterior is scratched on the hood and transformer cover, and paint is peeling. Serial 4810364 (Fujisawa Yukishi)
Maintenance information: 2020.8.25 maintained (50CA10 x 3, 12BH7 x 1, coupling capacitor, electrolytic capacitor, rectifier diode, semi-fixed resistor, RCA terminal, SP terminal, MT tube socket, fuse replacement. Gain VOL, impedance switching SW disassembly contact refinement, oxidation and sulfidation prevention grease coating circuit readjusted, input/output waveform confirmed, rated output tested)
Accessories: No accessories
Main specifications: used vacuum tube 50C-A10 x 4 12BH7A x 2 6267 x 1 EF86EH x 1 output 25+25W (4/8/16 ohm switch switching) speaker output 1 system W410 x H160 x D205 mm 13.8 kg
Thorough maintenance was carried out, such as replacing capacitors and deteriorated parts! A custom model whose circuit was changed from the original to a non-feedback amplifier. The output drops by 5W+5W compared to the MQ60, but surprisingly, this one has a better amount of noise, and the sound quality is clean. The appeal is that it is easy to grasp the sense of localization. The exterior has a feeling of use such as dullness. Serial 40401535 (Tomonori Asaine)
Maintenance information: 2024.10.27 Maintained (vacuum tube socket, block capacitor, electrolytic capacitor, oil capacitor, SP and RCA terminals, semi-fixed VR, fuse, spark killer, diode, micro SW replacement. Load test, input/output waveform confirmation impedance switching SW/gain VOL decomposition contact refinement, application of anti-oxidation/sulfidation grease, input/output waveform confirmation, load test (1kHz sine wave, at 8Ω load: 25W+25W), sound output test)
