FA 2500T
Tube amplifier

2500 watt output power in uninterrupted service this amplifier can work with full power in uninterrupted service (24 hours a day).

Only 65 watt excitation are enough to achieve full power output

Easy adjustable output power by means of the variation of excitation power.

Single tube: the use of only one electronic tube has permitted to obtain a device with a simple and strong structure, an excellent reliability and a very long performance stability.

Long life tube: being a triode it is mechanically and thermally very strong. Besides its particular kind of polarization makes the exploitation of the tube (18 months average life) excellent.

Electronic protections: the presence of electronic protections guards the tubes from those accidental events such as the load disjunction, the ventilation system fault, the over consumption or the over driving which can damage the tube in an irreparable way.

Contained wattmeter and SWR meter. the device contains a wattmeter and a SWRmeter, allowing in this way the adjustment and the control of the regular working without particular instruments.

Filament voltage adjustment: this control is adjustable from the outside, permitting to control and adjust accurately this parameter, which is determinant for the life of the tube.

Wide band input. The input is untuned so that the frequency change is very simplified.

Output low pass filter guarantees an output signal with pure spectrum at any working frequency.

Automatic start-up. The regular start-up procedure is automatic so that thermal shock due to the driver or to the anodic voltage application before the tube warm-up is avoided.

Provided with air filter. the filtering of the air permits the working in dusty places, reducing the frequency of the ordinary maintenance (for the cleaning of the tube and the inside).

Rack cabinet with drawers: the amplifier is divided in two sections, radiofrequency and power supply, contained in two separated drawers. The cabinet is also provided with the fitting places for the exciter and the driver, so that the unit is very compact but also easily accessible and easy to move in case of repair.
