The price has been reduced. 2024/1/17 sales price 398,000 yen Maintained! It is a model that was sold between the first stereo preamp C20 and Tubyu's last preamp C22, and was only sold for a very short period of time. The highly perfected sound made during the maturity period of vacuum tube amplifiers, which is a bit different from the C20 and C22, is attractive. There are small scratches, dullness, etc. appropriate for the model year (Oikawa Tetsuji)
