Faithful reproduction of the original sound source

Astro Denshi Kikaku's products have a beautiful appearance made of vacuum tubes and metal processing, and a rich amount of information and high purity sound quality to faithfully reproduce the original sound source. Carefully selected materials are carefully crafted one by one by skilled artisans. The internal parts of the amplifier are carefully selected and manufactured by the same skilled craftsmen as those used in high-end models, resulting in an amplifier that produces high-quality music reproduction similar to that of high-end models.

The TO-KG series is even more compact than the mid-sized TO-FC series, with a width of 20 mm. The TO-KG series is made of 52S aluminum alloy 2 mm thick, with two types of anodized chassis (champagne gold and silver), and by producing and processing internal parts mounting fittings exclusive to Astro Electronics Planning and making them double, resonance is The sound quality has been improved while suppressing resonance. The appearance of the anodized aluminum front panel, which is made of 10mm-thick 52S aluminum alloy, and the knobs for the VR are also anodized to create a fascinating amplifier that accentuates the shiny vacuum tubes.

The output tubes are equipped with a self-bias function, so they can be easily replaced with compatible bulbs for your enjoyment. The self-bias capacitor used by Astro Denshi Kikaku is an order of magnitude larger than the 200~300 micro capacitors used by most manufacturers, at 8000 micro. 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, etc. without a preamplifier and enjoy high quality tube music at your leisure.
The push-pull TO-KG series delivers a dynamic and powerful sound, with a push-button bass, rich mid and high frequencies, sharp attack on piano and brass instruments, and realistic vocals. The transparency of the sound and the texture of the sound image are more than worth the price.

The transformers are made of original transformers that keep the price as low as possible while the sound quality is close to that of high-end machines. The legs are made of a combination of aluminum and rubber materials. The circuit parts and chassis mounting parts are also made of carefully selected materials in pursuit of high sound quality, and a two-stage internal structure is used to achieve good sound quality.
