Beschreibung

Die B443 von Philips ist die erste serienmäßige Endpentode der Welt - erschienen im September 1927. Verstärkung und Leistungsabgabe war deutlich größer als die einer vergleichbaren Endtriode. Die B443 hat die Verdrängung der Endtrioden durch Mehrgitter-Endröhren eingeleitet. Die entsprechende Telefunkenröhre RES174d gibt es erst 1931.

Hi,

I have a B443N. See the attachment. I haven't found a page for it.

Did I miss something?

Best regards,

Ottó

Hi Ottó,

a B443N is nowhere mentioned and its meaning is unknown, perhaps it is due to its vertical structure.

A page for it is now created.

Best Regards,
Jacob

B443N Tube 

Good morning Ottó and Jacob

I started an inquiry in the Dutch Radio-Forum about this tube.

Because the original one was on the market as from 1927, the 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.

Regards

B443N Tube 

Hello everybody,

My assumption was in the right direction, as the vertical structure is a modernised version.

At Philips tubes the suffix "N" indicates a new, modernised or improved version of a tube.

Best known is the EL3N, an improved version of the older EL3. Today one can find much more EL3Ns then the original EL3. As soon as the EL3N appeared, it has completely displaced the EL3 !

In contradiction to EL3 vs. EL3N is this the first time I saw a B443N ever. The production number of B443Ns must have been quite low.

Best Regards,
Jacob

In addition to what is said above:
Later on, Philips produced the improved EL3N but often left out the letter "N".

La valvola B443 viene utilizzata anche per il modello 6 della radio Televox_CH 6 anno 1925

Probabilmente la valvola B443  utilizzata nel modello 6 della Televox é stata sostituita all'originale.

Sarebbe opportuno trovare lo schema  o la documentazione  dell'epoca per vdere quali valvole venivano impiegate all'origine. L'apparecchio della mia collezione data del 1925.

Hallo Gian-Fausto,

This is impossible, since the B443 was introduced in September 1927.

Ciao Gian-Fausto,

questo è impossibile, poiché il B443 è stato introdotto nel mese di settembre del 1927.
