ASTOR AS-300BsSPII. Vacuum Tube Single Power Amplifier

The chassis of the AS-300BsSPII. 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 with anodized aluminum. This sturdy and beautiful mirror-finished casing 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-300BsSPII. is characterized by the use of 5881 tubes that carry a current of 20-25 mm and produce 50 W if it is a push-pull amplifier, instead of the 12AX7 and 12AU7 tubes that usually flow a current of 3-4 mm for the second stage driver tube, which easily drives the 300B tube. 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.
