This amplifier is developed to increase the FM signal level in the 87,5 - 108 MHz range.
The rated output power is 900 W.
The apparatus is designed with tube technology.
It uses one "EIMAC" tube, which assures high gain, very long MTTF (mean time to failure) and easy replacement.
The internal structure is modular designed in a single frame-work, and grants accessibility dismounting the front panel and opening the back door.
It's also very stable. The input circuit is broadband, being grid grounded.
The controls for tuning and adaptation of the plate, load, input frequency tuning and input coupling, are motorized.
This allows an easy tuning of the entire frequency range, through the front panel.
It includes protection circuit to control: high SWR, high temperature, high plate's current, high grid's current, low ventilation, irregular voltage of polarization, irregular voltage of filament, irregular three-phase supply, damaged motor of fan, irregular closure of panels, line over voltage of and high temperature of transformer.
