Astro Electronic Planning AST-300BMg Vacuum Tube Stereo Single Power Amplifier

ASTRO ELECTRONICS, a vacuum tube amplifier manufacturer, will develop a new series that has been reborn from a line-up with a full-size weight, narrowing the width and reducing the size of the amplifier, without sacrificing sound quality, to a lightly handling easy amplifier.

The transformer adopts an original transformer that plays sound quality that is unbeatable to advanced grade while reducing the price. The legs are aluminum and rubber. By using carefully selected materials for circuit parts and chassis mounting parts, high sound quality is pursued, and the internal structure is made into two stages to prevent resonance from inside and outside, contributing to high sound quality with high transparency without noise.

With the self-bias function, you can easily replace various 300B manufactured by vacuum tube manufacturers around the world and enjoy the sound of each 300B. Also, since the LED is installed in the vacuum tube connection, it is a new vacuum tube amplifier that looks colorful. The color of the LED can be green, blue, red, or none.

For self-bias capacitors, AST-300BMg uses 3300 micros and different digits for those with 220-400 micro capacitors used by common power amplifiers. By using a capacitor with a large capacity, it can afford current capacitance, so it performs comparable to fixed bias. The sound is expressed firmly even when the volume is narrowed. Since the volume adjustment of left and right independent is attached, even without preamplifier, you can easily enjoy high-quality vacuum tube music by connecting directly with CD player, smartphone, tablet etc.
