2021/12 POWER amplifier LEVEL volume x 2 replaced, main VR disassembly, cleaning, etc. maintenance completed. The power supply lamp was converted to LED in September 2020, and full maintenance was completed, such as replacing transistors, capacitors, fuses, heat dissipation sheets, IC relays, resistors, semi-fixed resistors, diodes, power supply SW/SP terminals, etc. The second-generation premain amplifier for NEC's masterpiece A-10. Occasionally, it makes a surprising sound that touches the strings. It drives jazz and rock briskly with thick low frequencies and clear mid-high frequencies. Another reason for its popularity is that it is easy to separate power from pre. There is a feeling of use on the exterior, such as stains and dullness on the left side of the front panel, scratches on the VOL, paint peeling, etc. Serial 04Y0959 (Takasaki Atsushi)
