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 1980’s. 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.
Original JAN specification 5U4GB made in the USA by Philips to the highest military specification. The valve provides the exact rectification and long life as you would expect from a military grade valve. In many users opinion the Jan 5U4GB was the best of its type. The valve features a ruggedised vibration proof box black anode construction, Top and side getter to ensure that gas free evacuation was achieved and to maintain the vacuum at its best. The valve has a high grade filament isolation so even after long periods of use the filament will not degrade.
Finally, all these were run through the tightest quality control procedure to gain military acceptance.
The valve also has a higher current capacity than a 5U4G and so is many players first choice in Mesa Boogie Dual and Triple rectifiers and vintage Fender amplifiers.
This is an excellent 5U4GB and superb in all applications and guaranteed to outlive and outperform all of the current made rectifier valves.
5Z3P & 5Z3PA is a Chinese valve with an octal bass. The we have found the straight sided 5U4GB to be superior. So make sure your items has an octal bass if you are considering this item.
