It uses a GU-74 (4CX800) tube and the amp will come with a new old stock spare final tube. There's probably only 50 hours total use - I basically only used it to check into the 75m RACES net on Monday night. The amp will put out a solid 900 watts (solid carrier) or so with about 50-60 watts input and it can be serviced by DX Engineering if ever required. DXE sells this amp for $2,759, I would like to get $1,900 for it to save my marriage when the XYL sees the bill for the new amp ;-) It comes with a plug for 220V (it will only run on 220V.) I'm selling it because I have an Elecraft KPA1500 on order. The Acom is almost bullet proof with protection built in. It's super easy to tune up - just follow the instructions on the digital display. If anybody is interested I'll be happy to demonstrate in my shack. (I did quite a bit of research before I bought this 4 or 5 years ago, I think it's the best tube based amp on the market.) 73, de John WB5THT (cell 386-801-4878 or john at janeandjohn.org) ---------------------------------------------------------------------------------------------------- From DX Engineering: 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. A Svetlana 4CX800A (GU74B) 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 (no tuning, no switching); 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! Note: During and after your amplifier's warranty period, DX Engineering will provide service and repair for ACOM amplifiers. A repair fee will be charged for services outside the warranty period.

If you are ever in the market for a tube amp, the Acom 1000 is a winner. 73 de John WB5THT From keith at keithwatson.com Fri Jan 31 13:07:33 2020 From: keith at keithwatson.com (Keith Watson) Date: Fri, 31 Jan 2020 12:07:33 -0600 Subject: [HCARC] In need of an amp doctor Message-ID: I have an Ameritron AL-80B that needs some attention. I acquired this amp from the family of a silent key, so I don't know a lot of its history. When I try to run it at around 400 to 500 watts, it will randomly hiss at me and the power drops to zero. The very next transmission, it usually works fine. Sometimes, instead of a hiss, I hear a click and power drops off. I am hoping someone out there has some experience working on these things and give it a look see for me. 73 Keith...
