12AX7 by Yukio Miyamoto
Admiration is an inexhaustible pleasure. The 12AX7 has been in continuous production since its launch in 1947.
The 12AX7 is a high gain dual triode that will likely have been instrumental in making you resonate to amplified music; it is commonly found in the pre amps of most guitar amplifiers.
Valves/tubes are interesting because they radically changed the way we live. Around 1904 Englishman John Fleming, then of Edison, was considering why the filaments of Edison incandescent light bulbs always failed at the cathode end. He realised this was because the electrons boiling off the filament always flowed from cathode to anode thus diminishing the cathode. Fleming was the first to realise this flow could be manipulated in the process of radio and telephony amplification. Thermionic valves/tubes and their transistor successors were conceived.
Our t-shirts are unique for being wholly made with CoolMax freshFX. CoolMax is a patented fibre designed to wick perspiration and accelerate moisture evaporation, keeping wearers cooler and drier. This wicking feature of the fabric is made possible by micro channels engineered into the profile of and surface of the fibre. These channels are cleverly dimensioned to exploit the surface tension and capillary action of water. Being physical properties of the fibre, these channels endure and do not significantly diminish with wear or washing.
Antimicrobial (freshFX) treatment stops the propagation of odour producing bacteria. This is achieved by embedding silver salt crystals into the structure of the fibre. FreshFX treatment like the wicking is permanent and does not leach out with everyday use. These characteristics ensure the shirts remain cool, dry and odour free regardless of what you might do in them. Performance of the fabric is guaranteed through a certified and monitored manufacturing process.
