55 capacitors, 28 transistors, various switches, volume disassembly, cleaning, etc. have been maintained! 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 has stains on the top plate and dullness on the metal part (Ryo Mizusaki)
