ASTOR AST-6L6GCsSTK Vacuum tube stereo single power amplifier

vacuum tube amplifier manufacturerASTORA new series for beginners of vacuum tube audio has been born. By narrowing the width and reducing the size of the amplifier, we have created an amplifier that is light and easy to handle. AST's STK series uses the company's first original internal board to simplify manufacturing and reduce manufacturing costs and manufacturing time.

Astro Electronics' original board is designed with thicker wiring than normal boards, contributing to the amount of information and sound quality. In addition, by using the company's original design transformer, which is comparable to the high-quality Hashimoto transformer, we have succeeded in keeping the price down without sacrificing sound quality. Each tube amp craftsman carefully builds it one by one, resulting in expressive and powerful sound quality that will satisfy not only beginners but also enthusiasts.

There are two input systems, so you can connect a music player such as a CD directly without going through a preamp and enjoy authentic vacuum tube sound. In addition, by installing an LED in the tube insertion section, you can enjoy a new visual effect of a vacuum tube amp that has never been seen before.

Vacuum tube amplifiers require adjustment to stabilize the operating point (bias point) in order for the vacuum tubes inside the amplifier to operate optimally at specific voltages and currents.AST-6L6GCsSTKIt has a self-bias function that automatically performs the troublesome bias adjustment, so you can enjoy the difference in sound quality of each vacuum tube by replacing it with a compatible vacuum tube.

The self-bias capacitors used are 100 to 200 microns, compared to the 100 to 200 micro capacitors used in general amplifiers in the same price range.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-quality 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.
