Thank you for viewing. This is a Technics SU-C01 control amplifier. This product has been overhauled for normal use. ■ We have confirmed that it operates normally and without any problems. ■ All selectors and slide switches have been removed, disassembled, contact cleaned, slide contact-specific oil applied, reassembled, installed, and inspected. ■ Slide contact-specific oil eliminates oxidation and sulfidation caused by corrosive gases and the increase in contact resistance due to friction, extending the life of the contacts. ■ Furthermore, it is an excellent product that completely eliminates the worry of contact failure and does not damage the materials. ■ The resistance measurement value of the contacts after maintenance is 0.0Ω. ■ You can use it with peace of mind for a long time without worrying about contact failure. ■ Both the interior, exterior, and plug terminals have been thoroughly cleaned, so you can use it immediately upon arrival. The existing SU-C01 often exhibits symptoms such as poor contact in the selector, no sound output, noise, and deterioration of sound quality. Maintenance of the selector and slide switches is essential for normal use. This is a high-performance model with a luxurious specification, condensing high functionality into a compact body with good design and texture. The first stage of the MC pre-preamplifier is composed of low-noise transistors in a complementary push-pull configuration, achieving low noise, low distortion, and low output impedance. Newly developed low-noise transistors are used in the first stage of the phono equalizer section. By using a differential amplifier with a current mirror load that allows the selection of an operating current that minimizes the distortion level, the S/N ratio has been improved. The sound tends to be transparent, with a natural sound quality without any peculiarities, and it is a control amplifier that meets the needs of full-fledged use despite its compact size. The A4-size cabinet is made of precision-finished die-cast. All the knobs on the front panel are made of machined solid aluminum. Gold-plated terminals are used for the panel terminals.
