Wikimedia Commons has media related to OM2000+.
The OM2000+ is a linear power amplifier produced by OM Power[1]. The amplifier covers all bands used by shortwave radio amateurs. The amplifier has an amplification of 15 dB and a maximal output power of 2000 Watts. The integrated tube is the ceramic tetrode FU-728F.[2] The tube is aircooled.
The OM2000A+ is an identical power amplifier but with automatic tuning.
