About ACOM 1000 - Valve Amp 160-6m 1Kw

Acom 1000 HF plus 6m Amplifier

The ACOM 1000 gives you a comfortable 1000 watts output on all amateur bands from 160 through 6 meters.

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.

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 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. It would also not cease to function with a "soft" AC line and would 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

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.

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

We aim to dispatch all parcels within 24hrs. We are normally able to dispatch parcels SAME DAY where orders are received before 2.00pm Monday to Friday.


Whilst we try our best to ship same day, we cannot guarantee delivery time. You will however receive tracking details as soon as your order has been processed.


Please note that we do not process orders over the weekend, so orders placed after 2pm on Friday will not ship until Monday.


Please allow an extra processing day for international orders to enable us to complete export/import custom clearance declarations.
