Details such as 47 capacitors, 22 transistors, and complete VR and SW disassembly and cleaning have been refreshed. A flagship model from the 70s. Only this model has a very aggressive sound, and the sound comes out hot and forward. This is one car that makes jazz and rock sound crisp, thick, and exhilarating. Not only is the sound completely different from modern amplifiers, but the retro face is also attractive. The exterior is dull, but it is in a good category even when viewed from the model year (Oikawa Tetsuji)
