The ACOM 1000 HF Linear Amplifier is the world's best value in an amateur HF amplifier. The ACOM 1000 gives you a comfortable 1000 Watts output on all amateur bands from 160 through 6 meters.
Easy to operate

The plate-load True Resistance Indicator (TRI) is a powerful tuning aid which, together with the automatically controlled input attenuator, helps the operator to quickly and precisely match antennas (5-10 seconds typically). The auto-operate function (when enabled) maintains the amplifier in OPERATE mode for you, thus saving manual operations and time.

No antenna tuners

The amplifier will perform the functions of an antenna tuner for VSWR up to 3:1, thus enabling you change antennas faster and use them over a wider frequency range (saving tuning time).


An amplifier that is both user-friendly, and that looks after itself. It is designed to safely withstand up to 300 W 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. It also does not cease to function with a "soft" AC line and will deliver more than half power at only 75% of nominal mains voltage. Withstands up to 10 milliseconds (down to zero) voltage drops, and up to +15% line voltage spikes - important particularly when used at field day, on DxXpeditions, etc.

LCD comment display

Text messages,12 parameters, and strip peak-reading PEP meter displayed on a dot-matrix, back-lighted LCD. LED indicators are provided for OPERATE, attenuator-on, and ON/OFF conditions.

Easy maintenance

Signatures of the amplifier's internal status are stored in a nonvolatile memory for 7 most recent auto protection trips. This information is used for diagnostics.

Virtually silent QSK

The input bypassing and the vacuum antenna relays are very quiet even in CW mode due to their special mounting.

Broadband input matching

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

Single 4CX800A (GU74B)

A Svetlana high performance ceramic-metal tetrode with plate dissipation of 800 W is employed (forced air cooling, grid-driven).

Tube protection

Permanent monitoring and protection of plate and grid voltages and currents, as well as of the exhaust temperature.
