ACOM 1010 HF Linear Amplifiers
ACOM 1010 HF Linear Amplifiers cover all bands from 1.8 through 29.7 MHz. They provide over 700 W PEP output (or 500 W continuous-modes) with less than 60 watts of drive and operate without special transceiver signaling; they need only "ground on TX" and the required drive. ACOM's exclusive True Resistance Indicator (TRI); enables faster antenna changes and use over wider frequency ranges. Also, a built-in antenna selector switch with two outputs is included to provide instant choice of antennas. Antenna matching can be achieved in less than 10 seconds and at a quarter of nominal output power, which results in lower risk of interference to other stations and greater safety to the amplifier components. A single ACOM 4CX800A high-performance ceramic-metal tetrode with plate dissipation of 800 watts is used for maximum efficiency. These amplifiers are self-monitoring. They are designed to safely withstand up to 240 watts of reflected power, up to 100 milliseconds of drive spikes (RF "tails" after a PTT or KEY release), and even operator tuning errors. They are also capable of operating at more than half their designed output at only 75 percent of nominal line voltage. Because they can tolerate deep voltage drops and 15 percent line voltage spikes, they are particularly well-suited for use in portable environments, such as Field Day and DXpeditions. Importantly, a variety of system parameters are continuously monitored and available to the operator to assure safe and efficient amplifier operation. Design of the high-voltage power supply eliminates the danger of turn-on transients affecting sensitive devices connected to the same line (mains) circuit. Moreover, the amplifier can be configured to accommodate any of eight nominal line voltages between 100 and 240 V, 50 or 60 Hz. Please see the SPECIAL Note, below.

ACOM 1000 HF + 6 Meter Linear Amplifiers
ACOM 1000 HF + 6 Meter Linear Amplifiers are the world's best value in an Amateur HF amplifier. These amps provide you a comfortable 1,000 watts output on all amateur bands from 160 through 6 meters. The plate-load True Resistance Indicator (TRI) is a powerful tuning aid which helps the operator to quickly and precisely match antennas. The auto-operate function (when enabled) maintains the amplifier in OPERATE mode for you, saving on manual operations. Broadband input matches to the transceiver over the entire range of 1.8-54 MHz. ACOM 1000 amplifiers are both user-friendly and look after themselves. They are designed to safely withstand up to 300 watts reflected power, drive spikes of up to 100 milliseconds duration, drive RF "tails" after a PTT or KEY release and the operator's inadvertent tuning errors. They also withstand a "soft" AC line and will deliver more than half power at only 75 percent of nominal mains voltage. They can withstand voltage drops for up to 10 milliseconds, and up to 15 percent higher line-voltage spikes. These details are all important, particularly when used at Field Day, on DXpeditions and other portable operations. Be sure to read the SPECIAL Note, below. An ACOM 4CX800A high-performance ceramic/metal tetrode with plate dissipation of 800 watts is employed. On-board processing provides permanent monitoring and protection of plate and grid voltages and currents, as well as the exhaust temperature. Text messages, 12 different parameters, and strip peak-reading PEP meter are displayed on a dot-matrix, back-lighted LCD. LED indicators are provided for OPERATE, attenuator-on, and ON/OFF conditions. Records of the amplifier internal status are stored in nonvolatile memory for the seven most-recent auto-protection trips. This information is very valuable should diagnostics be needed. The input bypassing and the vacuum antenna relays are very quiet even in CW mode due to their special mounting. This results in virtually noise-free QSK! ACOM-1000 details: * Frequency Coverage: 1.8-54 MHz * Power Output: 1,000W PEP or continuous carrier; for continuous carrier transmissions longer than 15 minutes the external auxiliary fan must be installed * Intermodulation Distortion: Better than 35dB below rated output * Hum and noise: Better than 40dB below rated output * Harmonic Output Suppression: 1.8-29.7 MHz; 50dB below rated output, 50-54 MHz; 66dB below rated output * Input and Output Impedances: Nominal values: 50 Ohm unbalanced output; Input circuit: broadband, VSWR less than 1.3:1, 1.8-54 MHz; Bypass path: VSWR less than 1.1:1, 1.8-54 MHz continuously * RF Gain: 12.5dB typically, frequency response less than 1dB (50-60W drive power for rated output) * Primary Power: 170-264V (200, 210, 220, 230 and 240V nominal taps), 50-60Hz, single phase, 2200VA consumption at rated output. 230 or 240 volts recommended for USA * SPECIAL Note: Order part number AOM-1000 to wire the AC plug and voltage selection yourself; order part number AOM-1000-240 for pre-wired 240 volt operation or part number AOM-1000-120 for pre-wired 120 volt operation * Complies with CE safety and electromagnetic compatibility requirements as well as FCC-regulations * Size: 16.6 x 14 x 7.2 in. * Weight 58.5 lbs. * Operating environments: Temperature range 32 to 122 degrees F, Humidity up to 95 percent at 95 F * Altitude: up to 3,000m (10,000 ft.) above sea level without output deterioration Note: For additional information, please look at the files under the "Documentation" tab. ACOM says that these are the "world's best value" in an Amateur HF amplifier. Order one of these ACOM 1000 HF + 6M Linear Amplifiers from DX Engineering and decide for yourself!

American Beauty Resistance Soldering Systems
American Beauty Resistance Soldering Systems offer the most advanced and complete line of resistance soldering systems available anywhere in the world. You'll find power ratings between 100 and 3,000 watts, and various tool styles and compositions. You may use them to work on anything from tiny hobby/craft projects to soldering large copper plumbing. Here are just a few of the advantages: The concentrated heat reduces soldering time by many times over. Poor solder joints are often the result of insufficient heat throughout the joint, creating weak spots; these systems eliminate such problems. Traditional soldering methods may introduce too much heat into surrounding areas, damaging critical components or de-soldering previously soldered joints. Using resistance soldering systems will improve quality and reduce waste! Resistance soldering systems are ergonomic and versatile. Lightweight hand pieces cool within seconds, greatly reducing the likelihood of repetitive strain-injury and virtually eliminating the burn risk for the user. Versatile systems allow for easy access to restricted areas on circuit boards and inside cabinets. Resistance soldering systems can save you money! Instant heat means you're not paying to heat a soldering station all day long. Electrodes last twice as long as soldering tips and don't require constant re-wetting, thereby reducing consumable waste. American Beauty Resistance Soldering Systems get the job done. Stop trying to perform your difficult soldering operations the same old way with the same old tools. Contact DX Engineering to own of these American Beauty Resistance Soldering Systems today!
