Ameritrons compact AL-800 / AL-800H amps are both desktop linears with plenty of muscle!
At 14.25" x 8.5 x14.5", the more compact AL-800 uses a single 3CX800A7 to provide 1250 Watts PEP SSB and 850 Watts CW with 85 Watts typical drive level.
And the AL-800 will even run from a 20-Amp 120 VAC line source if desired. AL-800 typically draws 17 Amps peak current at 120 VAC, or 8 Amps at 240 VAC and weighs just 51 lbs.
For more power and headroom, the AL-800H uses a pair of 3CX800A7 tubes to easily provide 1500 Watts PEP/CW with a typical drive level of just 55 Watts.
The AL-800H draws 14 Amps peak current at 240 VAC (1500 Watts CW output) and weighs just 52 lbs. Other than power differences, these amplifiers are very similar in features and operation. Both cover 160-15 Meters, and are modifiable to cover 12/10 M with proof of your FCC license.
Both include a Step-Start input power circuit, a time delay circuit to allow for tube warm-up, thermal overload protection, grid current limiting to protect your tube(s), a DynamicBias circuit and a built-in multi-voltage (14 user-selectable AC line voltages from 90-140; 200-250 VAC) heavy duty power transformer. Hefty 32 lb. grain orientated silicone steel core transformer.
Front panel monitoring and tuning functions are also virtually identical. Both amplifiers include a Standby/Operate switch for barefoot or full power operation, an ALC SET control, Transmit and Fault LEDs.
Dual LED illuminated Cross-Needle meters provide detailed monitoring of amplifier performance. The left meter continuously measures grid and plate currents, and the right meter continuously measures peak RF output power on one scale, and plate voltage, Reflected power and SWR, ALC voltage, and ALC adjustment set.
