ASTOR AST-6L6GCsSTK Vacuum Tube Stereo Single Power Amplifier

Vacuum tube amplifier manufacturerASTORA new series for vacuum tube audio beginners has been born. By narrowing the width and downsizing, the amplifier is lightweight and easy to handle. In AST's STK series, by using the company's first original internal board, manufacturing is simplified and production costs and production time are compressed.

Astro Electronics' original boards are designed with thicker wiring than standard boards, contributing to both the amount of information and sound quality. Additionally, by using the company's original designed transformers that rival the high-quality Hashimoto transformers, they have succeeded in keeping prices low without sacrificing sound quality. Each tube amplifier is carefully crafted by our tube amplifier artisans, resulting in expressive and powerful sound quality that satisfies not only beginners but also enthusiasts.

There are two input channels, allowing you to directly connect to music players like CDs without a preamp to enjoy authentic tube sound. Additionally, by embedding LEDs in the vacuum tube insertion section, you can enjoy a new visual effect of vacuum tube amplifiers unlike anything before.

For vacuum tube amplifiers, it is essential to stabilize the operating point (bias point) of the vacuum tubes inside the amplifier to ensure optimal operation at specific voltages or currents.AST-6L6GCsSTKIt comes with a self-bias function that automatically adjusts the troublesome bias, allowing you to swap compatible tubes and enjoy the differences in sound quality of each tube.

The self-bias capacitors used in typical amplifiers in the same price range have capacitors of 100~200 microns,AST-6L6GCsSTKuses a capacitor with a large capacitance of 470 microns. This allows the sound to be clearly expressed even when the volume is turned down, whereas general amplifiers cannot express the sound properly when the volume is low. Since the left and right volume controls are independent, you can finely adjust the volume and enjoy the sound of vacuum tubes.High-FidelityYou can enjoy music easily.

The input terminal is a high-grade gold-plated terminal, and the speaker terminal is a machined aluminum gold-plated terminal that is compatible with a variety of speaker terminals.This is a full-fledged model that is compatible with speakers from 4Ω to 8Ω.
