RF output levels; SSB 800W+ (900W, typically), CW 600W
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"

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 or used Ameritron AL-811 series linear amplifier from anyone or anywhere to make sure that all necessary upgrades have been properly completed, especially regarding the amplifier's parasitic suppression circuit design!
