When the usage of tube amplifiers were blooming in the 1960s, the smaller 5 to 30 watts tube amplifiers were used at home and in small clubs, while bigger tube amplifiers that ranged from 45 to 100 watts were used in the larger concert stages. Among them, 15-20 watt tube amplifiers became popular due to its compact size mobility while maintaining its tube driven characteristics, and they have become increasingly demanded for various environments such as live performances and recording situation especially in modern times. Tube Craft hits the sweet spot with 15-watt output as its first project to reflect these needs in various environments.
Full Tube 15-Watts
For the power section, dual EL84/6BQ5 tubes were used. Famous for its splendor and delicacy, they are used to express the essence of the famous vintage British amplifiers. The preamp section uses three 12AX7 tubes to implement input gain, equalizer, effect loop, and phase inverts. The 12AX7 tubes, with its high voltage gain, are well-known for its natural yet rich overdriven tones that pretty much defines the rock guitar sound from the 1950s to today.
Speaker Design by Moollon®
With conventional speakers, we were not able to find the right tone we wanted to implement, and it was inevitable that we needed to develop a special speaker dedicated to Tube Craft. Designed by Moollon®, Tube Craft’s speakers are designed to best represent the rich dynamics and natural compression of the tube amplifiers. Modeled after the legendary speakers made by British companies in the 60s, the materials for frame, magnet, damper, cone, and dust cap were carefully chosen and rigorously tested to construct an eccentric ceramic-magnet based 30 watt speaker that expresses the delicacy of the vintage speakers.
Hand-wiring is a time-consuming process that requires expertise, which often times is avoided in mass production models due to poor productivity. However, it is an essential way to build an amplifier for higher stability in tone quality, often implemented by boutique amplifier companies. Hand-wiring ensures the stability of tube circuits that require high voltage, thereby providing the best performance in any environment.
The metal chassis is made of light, highly durable aluminium, making it less heavy to carry around while being resistant to external impact deformation. The cabinet is made of robust birch plywood, wrapped with ebony and ivory color tolex that’s dust and water resistant. The three stripes represent the intensity of racing vehicles.
