  • Tuned input coils
  • Please limit the transmit tune up periods to 5 seconds, each time. Allow the tubes to cool for at least 10 seconds in between each tune up period. 
    To tune up, firstly adjust the tuning capacitor for maximum RF power output possible with only 5W of drive, then un-key.
    Next, adjust the loading capacitor in one direction only (to increase loading) for maximum RF output, then un-key. If the RF output level reduces when adjusting the loading capacitor, then reverse the direction of adjustment. Keep repeating this two-step process, using drive levels of 5W, then 20W and finally 50W.
    Always tune and load to achieve the maximum RF output possible. Don't adjust both the tuning and loading capacitors during any one tune up period.
Lothar, VK1LS, says...
 
"The AL-811HD is a magic linear"

                      NOTES

Insurance cover for goods in transit is available from us for only $2 per $100 value of goods. Please advise us if you require this option when ordering.

Please consider insurance because we are not responsible for loss of parcels or damage sustained by parcels - the carrier is responsible! We do pack well!

Please do NOT write <fragile> on anything you send to us as doing so greatly increases the risk of damage. Please try to "double-box" all items sent to us.

Warranties are not transferable. We don't offer replacement warranties.
Customer-caused damage is not covered by warranty, of course.

Please ensure you select the same band of operation of your linear amplifier as the band of operation of your transceiver. Also, please ensure that your amplifier's relay line is connected to your transceiver's relay socket.

We can repair your AL-811 series amplifier. We can greatly improve its stability, too! Contact us now!

Lee recommends that if you're considering purchasing a new Ameritron linear amplifier from an Australian competitor make sure it is guaranteed to be new and that all necessary upgrades have been completed. Good luck...elsewhere.

Andrews DX-1600 series of linear amplifiers

The DX-1600 is a class AB1 passive grid high power RF amplifier using the Svetlana 4CX-1600B external anode ceramic tetrode valve. This amplifier is a combination of the latest technology, the best components and state of the art circuit design. The result is truly world class.

We are currently not manufacturing these amplifiers and regret that we have no stock of them. We occasionally have good used examples in stock.

The 4CX1600B is an extremely rugged, high gain and highly linear valve made in Russia. These factors made this Svetlana valve and also the GU-91b our first choice for consistent and excellent performance with low drive and very high RF output power.

Specifications

  • Frequency range: 1.8 through 29.7Mhz inc. the three WARC bands.
  • Circuit type: Passive grid, class AB1.
  • Cooling method: Dual speed fan forced air ducting and cooling
  • Dimensions: 500mm x 500mm x 225mm
  • Input impedance: 50 ohms unbalanced
  • Modes: SSB, CW, AM, FM, RTTY and SSTV
  • Output impedance: 50 ohms, unbalanced
  • Plate voltage: 3.2kV, approximately
  • Power requirement: AC 240V, 50Hz @ 16A maximum current
  • Electron valve: Svetlana 4CX-1600B -or- GU91b tetrode x 1 pc.
  • Protection: Amplified ALC, over grid current alarm, over temperature alarm, soft and stepped AC start-up & AC input safety interlock.
  • RF connectors: Two UHF (SO-239) sockets.
  • RF input: Less than 100W for full RF output.
  • RF output: Approximately 2000W SSB, 1500W CW.
  • Weight: 36Kg, approximately
