alpa-9500 power amplifier



The Alpha 9500 is no ordinary linear amplifier. The Alpha 9500 is the culmination of over 40 years of design and engineering. The Alpha 9500 is an advanced technology, auto tuning, linear amplifier that effortlessly delivers 1500 watts of power with as little as 45 watts of drive.

ALPHA-9500 Specifications

Frequency coverage: All amateur frequencies from 1.8-29.7 MHz

Power output: 1500 Watts minimum on all served bands

3rd Order IM: <-30 dBc

SWR tolerance: 3:1

Drive power: 45 - 60 Watts nominal for full power out

Tube: single 3CX1500/8877 type high performance power triode with a plate dissipation of 1500 watts provides key down performance on all frequency bands, all modes, and all duty cycles. 

Cooling: Forced air from two blowers

Antenna outputs: comes standard with 4 x SO-239 BIRD connectors, but can be changed to Type N easily from the back panel by removing 4 screws.

Antenna selection:  Internal 4 port antenna switch with 1 or 2 outputs per band/segment

Calibrated Wattmeter: The Bruene type wattmeter accurately simultaneously measures both forward and reverse power and displays this information on the easy to read bar graph meters on the front panel.  It also uses the information to simultaneously monitor the gain of the amplifier.

Protection Mechanisms: HV Interlock and Power Interlock.

Bypass mode: There are two power "ON" buttons on the Alpha 9500. "ON1" activates the Wattmeter and antenna selector without powering the amplifier itself, and sets the amplifier into "bypass" mode. The Amplifier is powered with the "ON2" button.

Input: Comes standard with an SO-239 BIRD connector, but can be changed to BIRD N Type easily from the back panel – order JCX-X130

Tuning/Band switching: Automatic plus manual override

Power: 100,120,200,220,240 VAC, 50/60 Hz, selection Automatic. At 240 VAC, requires 10 Amps per leg, for a total of 20 Amps.  Note: Although the amplifier will operate at 100V, the mains will have to be able to deliver upwards of 35 amps.

Interface: Serial port and USB. Full remote control capability.  

Protection: Protected against all common faults.

Display: Bar graphs display Power, SWR, Grid Current, Plate Current, Plate Voltage, and Gain - all simultaneously.  Digital Panel Meter can display Forward Power, Plate Current, Plate Voltage, Grid Current, SWR, Filament Voltage, and PEP Output. 

T/R switching: Two Gigavac brand vacuum relays enabling QSK (full break-in) at QRO (full power).

Bypass capability: 1500 Watts.

Shipping Weight: 76 Lbs

Product Size:  17.5"w x 7.5"h x 19.75"d

Standard Shipping Packaging: We ship this unit on a pallet, with the amplifier in one box, and the transformer in another.
