ASTOR AS-KT88sSPII. Vacuum Tube Single Power Amplifier

The chassis of the AS-KT88sSPII. is made of the same bent stainless steel 2mm thick mirror finish used in the high-end AS series, and the panels are made of 52S Geraldine 10mm thick panels anodized. This sturdy and beautiful mirror-finished casing alone costs nearly 200,000 yen, but it is remarkably effective in anti-vibration and noise countermeasures. The heat dissipation is also solid, so there is no problem at all even if you use it for a long time even though it is a tube amplifier. The insulator is also machined from a 40mm 52S round bar, and a young cowhide leather is sandwiched between it and the chassis to provide an anti-vibration effect. Circuit components are manufactured using components with good sound quality carefully selected by the company. The accuracy of the installation of the vacuum tubes is also extremely high, and the noise generated from the vacuum tube mounting part is suppressed as much as possible, and the artistic aerial wiring that eliminates waste, and Astro Electronics' unique manufacturing method technology greatly contribute to the high sound quality with high sound quality and no unnecessary decoration and faithful reproduction of the original sound without unnecessary decoration.

The AS-KT88sSPII. is characterized by the use of 5881 tubes that flow as much as 20-25 mm of current and emit 50 W if it is a push-pull amplifier instead of the 12AX7 and 12AU7 tubes that usually flow 3-4 mm of current in the second stage driver tube, which easily drives output tubes such as KT88 and 6550. The sense of power is further amplified, and the transparency and delicacy of a single amplifier while reproducing a crisp and powerful sound with a core. With the KT88, the mid and low frequencies extend well and express a large orchestra with a solid and powerful expression. If it is a 6550, the mid and high frequencies are well extended, and the clear and crisp expression is suitable for quartets and chamber music with a small ensemble.
