|Henry Radio 2K-Classic Amplifier|
|Category||Audio, Video, TV, Multimedia|
The 2K-Classic, 2KD-Classic, and the 2K-Classic X are a family of high quality one stage linear RF amplifiers using two rugged, economical, and proven glass envelope Eimac 3-500Z triodes operating in a grounded grid circuit. The amplifiers are completely self-contained and offer a choice of 2000 watt PEP input amplifiers using only the highest quality Components. The 2KD-Classic is a desk model Amplifier with a lighter duty power supply for the operator who is primarily intending SSB, CW or other non-demanding operation. The 2K-Classic is a floor console Amplifier offering a heavier duty power supply for the operator who is serious about contesting, rtty, slow scan, or other more demanding modes of operation. The 2K-Classic X comes in two formats a domestic version for sale in the United States, and an export version for sale outside the United States. There are two differences between the domestic and export amplifiers. The first is that all models of amplifiers sold in the U.S. are not supplied with a 10 meter band because of FCC regulations regarding Amplifier operation above 24 MHz. Also the domestic version is supplied with a smaller plate transformer because of FCC regulations regarding the maximum allowable output from an amplifier. The 2K-Classic X differs from the 2K-Classic by including a separate filament transformer/ heavy duty power supply section, a larger transformer (for export), and heavier Components in the RF section (bandswitch and coil). These are a family unit of amplifiers because they are all designed around the same basic RF deck design which employs a unique rotary tank inductor not found in any other line of production amplifiers. All of the amplifiers are designed for SSB, CW, RTTY, or AM operation on the amateur bands between 3.5 and 30 MHz (subject to 10 meter restrictions). The amplifiers can also operate on frequencies outside the amateur bands for military, commercial, or industrial applications.
