Used Acom 2000a automatic HF amplifier assembled in 2008 The amp is very good conditions and in perfect working order. The amplifier employees metal ceramic GU74b tubes and deliver full output power. More specifications from factory site.
Constant carrier modes 1500W RF output - no time limit with auxiliary cooling fan. Frequency coverage: All amateur bands 1.8-24.5 MHz. 28 Mhz only with modification by licensed amateurs. Bandchange / Tuneup: Initial output matching process in less than 3 secs (typically 0.5 secs).
Preset matching process / bandchange takes less than 0.2 second to move to different segment, same band and less than 1 sec for QSY to different band. Tuning memories: Non-volatile for up to 10 antennas per frequency segment. Drive power: Typically 50W for 1500W output. Input impedance: 50 ohms nominal. Output tolerance: Up to 3:1 VSWR (2:1 on 160m) at full rated output before SWR protection circuit actuates. Higher SWR's tolerated at lower output. Harmonics: At least 50 dB below peak output at 1500W.

Intermodulation: At least 35 dB below peak output at 1500W. T/R and keying: Vacuum Relay: QSK capable. ALC: Negative going, grid derived, -11v max, rear panel adjustable. Remote Control Unit provides flexible monitoring of all amplifier operating parameters. Protection: Grid and screen current limiting, power inrush (soft-start provided), trip to excessive reflected power, RF arcs, password access protection if needed, correct T/R sequencing, tube exhaust overheat, cover interlock and HV crowbar.

Fault diagnosis: Remote Control Unit display and LED's plus "INFO Box" for 12 most recent events. Transformer: 3.5 kVA with strip-wound Unisil-H? AC power requirements: 100/120/200/220/240 VAC nominal. 3500VA single phase at full power.

Physical: RF Unit: 17-1/4"W X 7"H X 17-3/4D. (440W x 180H x 450D mm). RCU: 5-1/4"W X 6-3/4"D X 1 H. (135 X 25H X 170D mm).
Plug in transformer for ease of installation and transport. No controls on RF unit except ON/OFF. RF unit may be located up to 3 metres (20m with optional cable) from RCU.
