From vacuum tube audio introducers to veterans

Faithfully reproduce original sound sources

Description

From Astro Electronics project of vacuum tube amplifier manufacturer, a new series was born for introducers of vacuum tube audio. By narrowing the width and reducing the size of the amplifier, it is finished to a lightly handling easy amplifier. AST's STK series uses the company's first original internal substrate to simplify production and compress manufacturing costs and production periods.

Astro Electronics original substrates are designed to be thicker than regular substrates, contributing to information volume and sound quality. In addition, the transformer has succeeded in reducing the price without sacrificing sound quality by using the company's original design transformer, which is no less than the high-quality Hashimoto transformer. Vacuum tube amplifier craftsmen carefully make it to the expressive and powerful sound quality that satisfies not only beginners but also maniacs.



There are two types of inputs, and you can enjoy full-scale vacuum tube sound by connecting music players such as CDs directly without preamplifying. You can also enjoy the new visual effect of the vacuum tube amplifier that has never been done before by installing LED in the vacuum tube insertion part.



Vacuum tube amplifiers require adjustments to stabilize the operation point (bias point) to optimize the vacuum tube inside the amplifier at a specific voltage or current.AST-6L6GCsSTKBecause it has a self-bias function that automatically performs troublesome bias adjustment, you can replace compatible vacuum tubes and enjoy the difference in sound quality that each vacuum tube has.

The self-bias capacitor used is 100-200 micro which is used by amplifiers of the same price range.AST-6L6GCsSTKThe 470 micro and capacitor are used. This means that the sound cannot be expressed properly if the amplifier is in a state where the volume is small, while the sound is expressed firmly even when the volume is narrowed. Since the volume adjustment of left and right independent is attached, you can adjust the volume finely, and you can easily enjoy high sound quality music played by vacuum tube.

The input terminal is a full-scale model that supports high-grade gold-plated terminals and aluminum-shaved gold-plated terminals for various speaker terminals and speakers from 4Ω to 8Ω.
