Use output pipe to driver stage

Single power amplifier using output pipe in driver stage


The chassis of the AS-KT88sSPU, use the same bending stainless steel 2mm thick mirror finish and those that are used in the high-end of the AS series, the panel subjected to anodized to 52S duralumin 10mm thickness panel use doing. This robust and beautiful mirror-finished casing alone has a lot of money nearly 200,000 yen, but it has a significant effect on anti-vibration and noise measures. Because the heat dissipation is also firm, it is not a problem at all even if it is a vacuum tube amplifier and long for a long time. The insulator also exhibits an anti-vibration effect by producing from a 40 mm52S round bar and sharply with a chassis. Circuit parts are manufactured using the company that is carefully selected by the company. The mounting accuracy of the vacuum tube is also extremely high, and the noise generated from the vacuum tube mounting portion can be suppressed as much as possible, and the unwanted artistic airline wiring, the unique manufacturing method of the Astro electron, the clearness of noises and is clear and transparent It is greatly contributed to reproducing the original sound with high sound quality and extra decorations.

The characteristics of the AS-KT88SSPU are not a 12AX7 tube or 12AU7 tube, which is commonly used in the second-stage driver tube, but a 20-25 mm current flows, and 50 W for push-pull amplifiers By using the 5881 tube that comes out, drives the output tube such as KT88 and 6550 easily. The feeling of power is further amplified and the single amplifier's transparency is high and delicated, and the core is scaled. With KT88, the Heterogeneous Orchestra is well extended and expresses strong power. If it is 6550, the middle and high-tone range is well extended, and the expression of the crease is not a small formation quartet or indoor orientation.
