Below there are described some main schematics on the miniature "pencil" tubes. The schematics came to us from the far 50- 60-s of the 20- Century. The schematics with pencil tubes were used at the radio equipment that was installed practically anywhere - from tank and submarine up to space ship.

Radio Frequency Amplifier

Figure 1 shows a typical schematic for a radio frequency amplifier. As usual a tube was used with plate voltage 60- V, second grid voltage 35- 45-V, and 0- V at the first grid. The RF- Amplifier works fine up to VHF- frequencies. (I.G.: I have seen such RF amplifiers that worked up to 180- MHz.) Practically any pencil tubes may work like a radio frequency amplifier.
