Carefully selected components

Faithfully reproduces 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 of 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.

TO-KT88FC is a push-pull type power amplifier, an Astro Denshi amplifier with enough power for your needs.
It has Astro Denshi's original noise processing and the highly transparent and unadorned original sound reproduction inherited from the high-end models, and it also has the broadness of nostalgia to handle any genre of music without any difficulty.
The TO-FC series is available with either four or six amplification tubes. The model with 4 amplification tubes uses a single driver for the second stage, split into left and right. The six-tube model uses a single driver on each side of the second stage in parallel to provide a margin of voltage.
The output tubes are equipped with a self-bias function, so they can be easily replaced with compatible bulbs for enjoyment. The self-bias capacitor used by the company is an order of magnitude larger than the 200~300 micro capacitors used by most manufacturers, but Astro Denshi Kikaku uses an 8000 micro capacitor. This allows the sound to be expressed well even when the volume is turned down.
The independent left and right volume controls allow for direct connection of a CD player, etc., and fine volume adjustment for enjoyment.

The chassis of the TO series is made of 2mm-thick aluminum, anodized in champagne cold silver. The TO series chassis is made of 2mm-thick aluminum material anodized in champagne cold or silver color, and 2mm-thick 52S alloy aluminum material is used for the component mounting material. Insulators are also made of a combination of aluminum and rubber materials. Circuit components and chassis mounting parts are also carefully selected for high sound quality. The internal structure is two-stage to achieve even higher sound quality.
