The last few units at the pre-increase price. There was a price increase of £250 on Jan 1st 2024 from Acom. However, we pre-booked extra stock orders prior to this to enable us to hold prices unchanged. Once this pre-booked stock is sold then our prices will be going up.

The GU74b tube fitted will be either Svetlana or Chinese origin depending on when the order ships. There is NO difference between the tubes (despite what other distributors might say to try to convince you otherwise), they are EQUALLY AS RELIABLE, dimensionally and electrically identical and completely interchangeable now and in the future. This is why we, The DX Shop, continue to offer a two year warranty on the TUBE as well as the amplifier on all Acom tube amplifiers.

The ACOM 1010 (A1010) is a self-contained linear amplifier that covers all amateur bands, from 1.8 through 29.7 MHz. It provides over 700 W PEP of output power (or 500 W in continuous-duty operation) with less than 60 W of drive.

Easy to operate
The plate-load True Resistance Indicator (TRI) is an ACOM innovation that provides quick and precise tuning, typically in less than 10 seconds. The AUTO-OPERATE function will return the amplifier to the OPERATE mode automatically after each protection trip, saving time and avoiding manual switching.

No antenna tuner needed
No external antenna tuner is required as long as the antenna SWR is 3:1 or lower. The amplifier will perform the functions of an antenna tuner, enabling you to change antennas faster and use them over wide frequency ranges.

User-friendly and durable
This amplifier is both user-friendly and self-monitoring. It is designed to safely withstand up to 240 W of reflected power, up to 100 milliseconds of drive spikes (RF “tails” after a PTT or KEY release), and even operator tuning errors. It is also capable of operating at more than half its designed output power at only 75% of nominal line (mains) voltage. Because it can tolerate deep voltage drops (down to zero for 10 milliseconds) and 15% line voltage spikes, it is particularly suited for use in portable environments, such as field days and DXpeditions.

LED bar-graph display
The upper LED bar-graph always reads peak forward power (except for the service functions) while the lower LED bar-graph is for the reflected power. LED warning indicators are provided for abnormal conditions of grid 1, grid 2, and plate parameters.

Antenna selection
Two antenna outputs are selectable on the front panel of the amplifier.

Efficient tuning
Antenna matching can be achieved in less than 10 seconds and at a quarter of nominal output power, which produces lower risk of interference to other stations and greater safety to the amplifier components.

The amplifier operates without special signalling from the transceiver. It needs only “ground on TX” and 60 W RF drive power to operate at full output power.

Broadband input matching
Broadband input matching circuitry offers excellent loading characteristics for the driving transceiver, from 1.8 MHz to 30 MHz.

Single tube operation
A single Svetlana 4CX800A (GU74B) high-performance ceramic-metal tetrode with plate dissipation of 800 W (forced air cooling, grid-driven) is used for maximum efficiency.

Permanent monitoring and protection of the plate and grids currents
The Bias Optimizer minimizes heat dissipated by the tube, assuring tube longevity.

High voltage protection
Design of the high-voltage power supply eliminates the danger of turn-on transients affecting sensitive devices connected to the same line (mains) circuit. Moreover, the amplifier can be configured for 8 different nominal line voltages: 100, 110, 120, 200, 210, 220, 230, or 240 VAC, 50 or 60 Hz.

Our 2 Year Warranty INCLUDES THE TUBE (unlike most other dealers) and is backed up with full factory-backed service and repair in our own workshops here at The DX Shop. No shipping to 3rd parties and long waits. After the warranty period ends units can be sent to us for inspection/quote/repair using OEM factory parts where needed that we source direct from Acom.
