1500W Output. 100W drive. The ultimate DX or EME amplifier For Radio Amateurs that need just that bit extra power for contesting, DXing or EME. The Linear AMP Uk 2m Discovery uses a GS35 triode which will produce up to 1500 Watts with about 80W of drive. The unit uses a 2.2kVA toroidal transformer with…
MODEL 10,000L – 10,000 WATTS (CW) 10 kHz – 100 MHz The Model 10,000L is a self-contained, broadband amplifier designed for laboratory applications where broad frequency range, high gain, and high power output are required. The combination of a high power internal load, specially designed, protective circuitry, and rugged liquid cooled tetrodes provides a truly…
ITB from Italy manufactures power amplifier modules, using state of the art 48V MRF6… transistors by Free-scale. These transistors make it very easy to have a linear amplifier at very high amplification levels. The efficiency of the modules is typically around 70%. The modules come pre-assembled and don’t require alignment. They are built on Teflon…
