ARTESOUND amps are constructed of only the highest quality materials: cabinets in 22 mm thick solid wood, aluminium chassis, oversized transformers to avoid stress, selected tubes, polypropylene or paper-in-oil capacitors and carbon composition resistors. All electric assembly is handmade with the point-to-point technique or turret board construction with specific wires to stand high temperatures. This guarantees that these amps produce high quality sound, exceptional strength and long life. In addition to this, ARTESOUND amps are also nice to look at. You can be sure that you are not only making a shrewd purchase but also a wise investment in a product that retains its value over time.
