What does the paper present?

In this catalog we sought to make available to technicians (now passionate about vintage electronics) - as much data on the characteristics of electronic tubes, so that they can be used not only for maintenance or repair of devices containing such tubes, but even when designing them.

In order for the use of the data in the tables, especially of the characteristic curves, to be possible for a wide circle of technicians (passionate about vintage electronics), the paper contains, in addition to the characteristic data, an introductory material in which it was sought to expose, in short, the necessary notions for the use of the data contained in tables and diagrams.
