- 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.

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. Let the buyer beware!

| 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.
