Description

Astro Electronic Planning, a manufacturer of vacuum tube amplifiers, has created a new series for beginners in vacuum tube audio. By narrowing the width and reducing the size of the amplifiers, they are lighter and easier to handle, and AST's STK series uses the company's first original internal circuit board to simplify manufacturing and reduce production costs and time.

Astro Electronics' original circuit boards are designed with thicker wiring than normal circuit boards, which contributes to the amount of information and sound quality. Also, by using the company's original high-quality products for all transformers, we have succeeded in keeping the price low without sacrificing sound quality. By carefully crafting each tube amplifier one by one, our tube amp craftsmen have created a sound quality with expression and power that will satisfy not only beginners but also enthusiasts.



There are two inputs, allowing you to connect a CD or other music player directly without a preamplifier to enjoy authentic vacuum tube sound. In addition, LEDs are installed in the tube inserts to provide a new visual effect never before seen in tube amplifiers.



The output tube has a self-bias function, so you can easily replace it with a compatible bulb and enjoy. The self-bias capacitor used is

While most amplifiers in the same price range use 100~200 micro capacitors, the AST-6L6GCsSTKuses a capacitor with a high capacitance of 470 microns, while most amplifiers in the same price range use a capacitor of 100 to 200 microns.This allows the sound to be expressed well even when the volume is turned down. The left and right independent volume controls allow you to connect directly to CD players, smartphones, tablets, and other devices to enjoy high-quality tube music without a preamplifier.
