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: 2024.11.22 Maintained (Vacuum tube 6AQ8 was replaced due to defective vacuum tube. Input/output waveform check, sound output test OK) 2024.6.21 maintained (vacuum tube socket, block capacitor, electrolytic capacitor, oil capacitor, 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
The disposal price has been reduced! (Member prices are not applicable) 2024/9/22 sales price 148,000 yen All switches have been disassembled and maintained, such as contact polishing! Comes with a cabinet. A preamp kit based on LUXMAN's CL32 tube control amplifier. It is designed so that the distortion ratio can be kept low. The fact that it has been made thin and stylish is also eye-catching. On the exterior, scratches are conspicuous on the VOL. Serial 006141 (Tamura Eiji)
Maintenance information: 2024.9.22 Maintained (all switch disassembly contacts polished contact grease applied. Volume disassembly operation contact polishing and cleaning. Replace the power inlet with a 3P terminal and replace the AC cord. Vacuum tube socket contact check. Capacitor check (maintenance replaced) each input/output operation check) 2021.10.12 manufacturer maintained (lead wire solder deterioration correction, volume base. Phono equalizer wrap ring capacitor defective replacement. Replace all other coupling capacitors that have deteriorated. (Other checks OK, some contacts cleaned)
Accessories: power cable
