Easy to operate
The TRI is a powerful tuning aid that, together with the
automatically controlled input attenuator, helps the
operator to quickly and precisely match the antenna
impedance to the optimum tube load impedance (5-10 seconds typically).
The auto-operate function (when enabled) maintains 
the amplifier in the OPERATE mode for you, thus
avoiding unnecessary manual operations.

No antenna tuners
No heavy outboard antenna tuners required for antenna
VSWRs up to about 3:1.  
Your amplifier will enable you to change antennas virtually 
instantaneously and allow you to use your antennas
over wider frequency ranges.

An  amplifier  that  is  both  user-friendly  and  that  looks
after itself.  It is designed to safely withstand up to 300W
reflected power, up to 100 milliseconds duration of drive spikes,
drive RF “tails” after a PTT or KEY release, operator’s
inadvertent tuning errors etc.     
The amplifier also will not cease to function with a 
“soft” AC mains and will deliver more than half power at only
85% of nominal mains voltage.
It can withstand voltage drops (down to zero Volts) 
for up to 10 milliseconds
and can tolerate 15% mains voltage spikes, which is especially
important on Field Day, during DXpeditions, and at portable operating
events where emergency power is relied upon.

Three antenna outputs
Three antenna outputs are selectable using a push-button
on the front panel.

Easy maintenance
Data  regarding  amplifier  internal  status  is  stored  in  a
nonvolatile memory for 7 of the most recent auto protection trips.
This information can be forwarded to your dealer for diagnostics.

Virtually silent QSK
The  input  bypassing  and  vacuum  antenna  relays  are
virtually  silent  even  in  the  CW  QSK  mode  thanks  to
specially designed mounting hardware.

Broadband input matching
Resulting in very good load to the transceiver over the
entire spectrum 1.8-54MHz.

Single 4CX1000A tube
Uses a ceramic and metal radial beam tetrode with plate
dissipation of 1000 W which is specially designed for class
AB1 RF linear amplifier operation.

Tube protection
Permanent monitoring and protection of plate and grid
voltages  and  currents,  as  well  as  of  the  exhaust  air

VFD comment display
All amplifier status indications are explained via detailed
text displayed on the dot matrix, high brightness vacuum
fluorescent display (VFD).  The upper line on the VFD always reads peak forward power.
LED indicators are provided for:  OPERATE mode, attenuation-on,
transmit, selected antenna output , and ON/OFF conditions.



un avis

J'ai eu l'occasion aussi de tester cet ampli.

Il fait un peu plus de bruit que l'acom1000

Le temps de préchauffage est un peu plus long que l'acom1000.
3 sorties antennes, cela dépanne, c'est pratique
Ses réactions sont excellentes , power input / power output.

L'accord tri fonctionne super bien , facile rapide

A nouveau acom a construit une rolls, superbe machine,
