Description
The SR series has a chassis made of 2mm-thick 18-18 stainless steel with mirror finish and internal components made of 2mm-thick 18-18 stainless steel with mirror finish and 2mm-thick oxygen-free copper material. The insulators are made of oxygen-free copper, machined from a round bar, and attached with young cowhide leather sandwiched between the insulators. The circuit components are manufactured using carefully selected parts that are good for sound quality.
All parts have been carefully selected and improved to ensure faithful reproduction of music.
The chassis has an adapter plate at the output tube socket to allow the use of a variety of output tubes, and its diameter opening further enhances heat dissipation and suppresses heat inside the chassis. The use of a top-quality Hashimoto transformer allows the reproduction of high quality sound with a natural extension of the low frequency range. In addition, the circuit configuration has been manufactured using high quality components that meet the requirements of the application in order to provide the best possible music listening experience.

Astro Denshi Kikaku manufactures vacuum tube amplifiers using matching transformers from the ultimate series of transformers for vacuum tube amplifiers by Hashimoto Denki (Sun-Sight transformer sales manufacturer), which is the result of combining tradition and the latest technology in transformers, which are the root of sound.
The self-bias capacitor used by the company is an order of magnitude larger than the 200~300 micro capacitors used by most manufacturers, whereas Astro Denshi Kikaku uses 8000 micro capacitors. This allows the sound to be expressed well even when the volume is turned down.
All of our products are handmade, so we can adapt them to your musical tastes and system to some extent!
