ASTOR SE-6550EL Vacuum Tube Push-Pull Power Amplifier

The chassis is 18-18 stainless steel mirror finish with a thickness of 1.2~1.5mm. The chassis is made of 1 mm thick 18-18 stainless steel mirror finish and 1 mm thick oxygen-free copper for internal mounting parts. The panel is made of 52S geraldine 5mm thick panel 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.

All transformers used are made by Astro Electronics, which is of the same quality or higher than that of Kanno Electric. Astro Electronics' original transformer is capable of reproducing excellent high-quality sound with a more natural spread and extension in the low frequencies.

By self-biasing, it is possible to enjoy a variety of sounds by freely changing the output tube of the same system. The self-biased capacitor used by the company uses an order of magnitude more capacitance than the capacitor used by general manufacturers. As a result, even when the volume is turned down, the sound is not lost and is expressed firmly.
