This
is a short list of the Philips and Fivre vacuum tubes I have
available. Its request is possibile just send me a message clicking Here.
Note that all forms unfortunatly are in Italian language only. For
an example, in this case of an ECH4
tube just click Here Remember
that all tubes listed above are RECEIVERS TUBES, so here you can't find
here some tubes as EL509 or similar that are high power tubes used
in TV color stages or linear amplifiers. If you are in the case to change
a tube with another similar but with a different socket don't remove the
original socket, keep it in place, this in order to don't damage the originality
of the radio. Here you can find a description table for EUROPEAN
tubes only. It is useful to know the internal funcions of some tubes from
its label.
