These are the original military grade JAN specification 12AX7WA that were made by General Electric in the USA for the American Government.
The GE valve was used extensively by all the major Audio manufactures such as Audio Research, Conrad Johnson and Fender all throughout the 70's and 80's under their own due to the valve exceptional sound quality.
Indeed Fender branded these and used these as standard in all those silver face Fender amplifiers. The USA made General Electric valve is very sought after valve by both guitarists and High end audio users due to the exception clarity and sound stage.
The General 12AX7WA has a clear and detailed top end and is very musical with especially fabulous midrange. What sets this valve apart from the rest is that is well balanced and smooth and it has the best top end response of any 12AX7 making it a great choice for Audio as well as guitarists of blues, jazz, and classic rock musical styles. In the opinion of many of the industry leading reviewers this is the best valve to use in Audio applications as they provide the original detailed and clear sound .
Audio Research and Conrad Johnson used General Electric valves for their sound quality and durability. The General Electric were chosen over many other famous factories as original issue for the above reasons. Jan specification items used the best quality nickel for the anode plates and highest quality internal components such as copper support rods. These items come in the original government boxes have the green government lettering with 12AX7WA USA acid etched into the glass.
