The Drake L-4B has 1000 watts PEP power input on AM, CW and RTTY and 2000 watts input on SSB. It covers 80, 40, 20, 15 and 10 meters (10 meters not available on late production). The high efficiency Class B Grounded Grid Circuit uses the new Eimac 3-500Z zero bias triodes. Power requirements are 115 V AC 50-60 Hz 30 amps or 230 V AC 50-60 Hz 15 amps. The included L-4 PS power supply (not shown) is in a separate enclosure. This amp features a quiet blower. There is a built in wattmeter calibrated at 300/3000 watts forward and 300 watts reflected.
