"The original B443 one was on the market as from 1927, this kind of internal construction was discontinued in the later years.

On the other hand, there was still a need for replacement in the older radio sets. So Philips started a new production line, but with a more modern technique. The letter "N" was added which means new, although the electrical performance should be equal to the genuine B443"
