ASTOR AST-300BMg Vacuum tube stereo single power amplifier

A compact single power amplifier that allows you to fully enjoy the 300B.

ASTORis introducing a new series with a narrower and smaller amplifier, replacing its traditional lineup of full-sized, heavy amplifiers. The AST-300BMg has been reborn as a lightweight and easy-to-handle amplifier without sacrificing sound quality. This model allows a wide range of users to enjoy the delicacy and expressive power of the legendary 300B vacuum tube.

Sound quality and robust construction comparable to higher grade grades

The transformer uses an original transformer that produces sound quality comparable to higher-end grades while keeping the price down. By using carefully selected materials for circuit parts and chassis mounting parts,High-FidelityPursue. Furthermore, the two-stage internal structure prevents resonance from inside and outside, resulting in high transparency and no noise.High-FidelityContributing to The legs are made of a combination of aluminum and rubber materials, taking into consideration vibration countermeasures.

High versatility and new visual effects

The self-biasing function allows you to easily swap out various 300Bs made by vacuum tube manufacturers around the world and fully enjoy the differences in tone. In addition, it has independent left and right volume controls, so you can connect directly to CD players, smartphones, etc. without a preamp.High-FidelityYou can easily enjoy vacuum tube music. Furthermore, by installing LEDs in the vacuum tube connections, you can enjoy new colorful visual effects that can be selected from green, blue, red, and nothing.

Achieves performance comparable to fixed bias

The self-bias capacitor used in this unit is 3300 microns, which is an order of magnitude higher than that of a typical power amplifier (220 to 400 microns). This large-capacity capacitor provides extra current capacity and provides performance comparable to fixed bias. As a result, the sound is clearly expressed even when the volume is turned down.
