Designed for the serious VHF/UHF DX, EME, digital and contest operator, the LA Series communications amplifiers are compact, 2-piece units including a desktop RF deck and a remote located high voltage DC power supply. The LA Series amplifier will produce 1500 watts (1200 watts for the LA-72A) of stable, reliable and highly linear (clean) output power. Their continuous duty ratings allows stress free and full power operation with all digital and traditional operating modes.
LA Series amplifiers use two rugged 3CX800A7 or 3CPX800A7 (pulse rated) ceramic metal triode type electron tubes. Silver plated plate RF circuits provide efficient power transfer and vernier drive controls enable smooth plate tuning action. The grounded grid circuit design ensures stable operation, high efficiency and maximum tube life. All models include front panel mounted tuning controls for easy setup.
Features include: Tube warm up delay, dual speed blower, complete metering, grid over-current protection, high SWR shutdown, ALC (Automatic Level Control) and HV sensing/inhibit for tube protection. Also included is a transmit/receive relay sequencer to drive the external RF T/R relay as well as control of other complementary equipment.
The complementary high voltage power supply includes a multi-tap transformer and is designed to safely reside under the operating desk or other remote location.
