Philips electronics components group was the name given to the products marketed in America after Philips bought the American valve manufacturer Sylvania in the early 1980ís. Sylvania was a major manufacturer of valves and Philips bought them to get the lucrative American Government and military contracts. These valves are of the highest military grade which offer outstanding performance and were all made in the USA.
The Original American made Philips 12BH7A is an excellent audio valve and is noted for its very warm and detail mid band and top end clarity. This valve was used by Ampeg as standard and was also used by many American high end audio companies such as Audio Research.

This valve also has a number of high grade features that set this valve apart from other 12BH7A as it was designed for military contract supply. The valve has four copper support rods through long plates with the box style centre rib and the large halo getter. The type number is set into the glass with the lettering USA.

Sound wise these valves display a warmth and clarity which gives a very open and dynamic sound.
The bass response is tightly focused and has a clear well extended range. The musical sound is very smooth and detailed which it brings any the system to life.
This is excellent in all Audio and guitar amplifier applications.
