AS-350BsLC chassis that does not put out any screws at all,using metal fittings of 2 mm thickness oxygen-free copper plate, folding processed 2mm thickness mirror finished stainless steel plate, by installing all parts, it becomes the same as the two-piece structure principle. In addition, it has made a remarkable effect on anti-vibaration and noise countermeasures.The insulator is manufactured from the round bar of 50mm oxygen free copper by scraping and it is attached with the young cow leather between the bottom plate.

Each circuit parts are carelly selected for high quality sound. Vacuum tube mounting accuracy is also extremely high, suppressing the noise generated from the tube mounting part as much as possible, wasteful artistic wiring eliminates noise pickup by wiring.

This ASTOR's proprietary manufacturing technology greatly contributes to faithful reproduction of the original sound without noise, high clear sound with no cloudiness, high transparency and no extra decoration. AS-350BsLCaims at reproducing the original sound which increased the thickness to the sound by using the choke coil, while expressing delicate and fine transparency by a single amplifier. For the transformer of the last stage, it is used a custom-made Hashimoto driver transformer of ASTOR design, power transformer is adopted for 20W.
