ACOM 1500: 1500 W PEP tube amplifier for 160-6 m with a single 4CX1000A tetrode.
Drive power: 60-85 W for rated output (the usage text says under 85 W); RF gain 13 dB typically, response flat within 1 dB
IMD: better than 35 dB below PEP rated output; harmonics: better than 50 dB (1.8-21.5 MHz), 66 dB (24-54 MHz); hum and buzz: better than 40 dB below rated output or 1% AM
Input SWR below 1.3:1, 1.8-54 MHz; bypass SWR below 1.1:1
Tube: single 4CX1000A / 8168 (1000 W plate dissipation, forced air, class AB1)
Withstands up to 300 W reflected power; fault signatures of the last 7 protection trips stored
Coverage: the current official product-page band list is 160, 80, 40, 30, 20, 17, 15, 12, 10 and 6 m; 60 m is not listed. The August 2021 user manual says "all amateur bands in the 1.8-54 MHz frequency range" without a band-by-band list and does not mention 60 m.
The August 2021 user manual requires the external auxiliary fan for continuous-carrier transmissions longer than 15 minutes; the current product page does not repeat this.
FCC ID X8NX8NAA1500 (granted June 2012); CE
