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)
