The disposal price has been reduced! (Member prices are not applicable) 2025/12/30 sales price 448,000 yen 220V specification! Please use the included transformer. Every corner has been maintained, such as replacing 12 capacitors and 6 resistors, and fixing the caulk on each terminal. Comes with a step-up transformer! A separate amplifier that is still popular even now, 70 years after its release. The thickness, luster, and tension of the sound are all emotionally composed, and perfectly express the sound of the instrument. Anyway, it is a famous machine with thick, firm mid-bass, and a tasteful sound unique to vacuum tubes. The external condition shows signs of use over time, such as damage, dullness, abrasions, etc. Serial 38204 66354/68312 (Yamato Yuki)
