Powerful, high purity sound quality and volume of information

More transparency and improved sound quality

Description

The chassis of the AS-6L6GSTG is made of 2mm-thick 18-18 stainless steel with a mirror finish, and the internal mounting parts are made of 2mm-thick 18-18 stainless steel with a mirror finish and 2mm-thick oxygen-free copper material. This robust and beautiful mirror-finished casing alone cost nearly 200,000 yen, but it is remarkably effective in anti-vibration and noise reduction. The heat dissipation is also very good, so even though it is a vacuum tube amplifier, it can be used for a long time without any problem at all. The insulator is made of oxygen-free round copper rod and attached with young cowhide leather. The circuit parts are manufactured using carefully selected parts that are good for sound quality. The vacuum tube mounting precision is also extremely high, and noise generated from the tube mounting area is suppressed as much as possible.

The unique manufacturing technology of Astro Denshi and the transformers are all custom-made by Hashimoto Denki, which greatly contribute to reproducing the original sound faithfully with clear and transparent high sound quality and no unnecessary decoration without any noise. The AS-6L6GSTG is 20W+20W, but even in a large room, it delivers powerful, pure sound quality and a wealth of musical information.
All 6L6 series tubes can be replaced without adjustment, so you can easily enjoy a variety of 6L6s.

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.
