General Description
The “Big Gun” is getting even bigger, with the new DX-3SP! With over 4000 Watts CW and more then 4500 Watts SSB, this QRO muscle amp is not a joke! It is an amplifier with gravitas capable of satisfying the serious and most fastidious station operator. All specifications and features, except output power, are the same all throughout the Emtron amplifier product range, and the DX-3SP comes complete with QSK module as standard. The design deploys two durable FU-728F tubes (improved Chinese mil-version of the 4CX1500B) in parallel, with a total plate dissipation of 3000 Watts, comfortably delivering the expected output power and durability. These robust FU728F tubes are manufactured in present production and are available directly from the manufacturer, or from Emtron, exclusively for Emtron amplifier owners. We believe that this New DX-3SP is physically the smallest 4000 Watt desktop RF amplifier on the market today, and the most popular as well.
Please note: This new DX-3SP comes with two FU-728B tubes, which are directly interchangeable with Eimac 4CX1500B tubes! Only the filament tap on the transformer must be changed from 9 volt to 6 volt, if Eimac tubes are used!
The DX-3SP operates at voltages of 200 to 240 AC at approx. 35 Amps. A 400 Volt two-phase transformer is also available!!!
Weight: 50 Kg (110 lb), shipped in two separate boxes, transformer and RF deck.
Dimension: 470w x 230h x 470d mm , (18.5″ w x 9″ h x 18.5″ d ) for RF deck.
Band Coverage
The Emtron DX-3 covers all nine amateur bands from 160 through 10 meters including WARC bands at full power. It utilizes a ceramic high quality 9-position band switch, separate individual position for each band. No band compromises like on many other amplifiers on the market. The LOAD and PLATE tuning employ 6:1 vernier reduction drives for precise silky smooth tuning.
Modes of Operation
The Emtron DX-3SP has been designed and built to operate in any mode such as: SSB, CW, AM, FM, RTTY and SSTV, as well as any other digital mode. QSK module included.
Output Power
This amplifier will comfortably deliver 4000 Watts (4500 Watts PEP) continuous carrier (“key down”) into your antenna. The conservative rating of the tubes, the tank and all other components, and the efficient cooling system allows effective operation at this power level.
Warranty
FOUR YEARS full warranty covers all parts and labour, and limited warranty on the tubes.
FACTORY DIRECT SALES AND SERVICE
The EMTRON DX-3SP is sold factory direct; no “middle man” mark up, you do business directly with the designers and producers; with skilled people who know the heart and soul of the DX-3SP, and will always be able to give you expert technical advice and after sales service.
So consider the biggest bargain in top brand 4 KW CW output linear amplifiers. The Emtron DX-3SP is the most technically advanced RF linear amplifier operating on all HF amateur radio bands, developed with quality, reliability, performance and price in mind. The DX-3SP model was especially developed by EMTRON for those discerning HAM operators who demand only the best. This tough power house will handle all the rigour and demands of contest, DX-ing and high duty cycle emissions.
