OM2000 +
The OM2000 + is a linear amplifier from OM Power , which covers all frequency bands of shortwave radio amateurs . The amplifier has a gain of 15 dB and a maximum output power of 2000 watts . The electron tube used is the air-cooled, ceramic tetrode FU-728F.
The OM2000A + is an identical linear amplifier that automatically adjusts itself when the frequency changes.
