    Overview and Key Features
    Power Output: Delivers up to 1.5–2 kW PEP on SSB and around 1.2 kW average on CW.
    Refinements: The “ZC” model is the final and most refined version of the LK-500 series, featuring a QSK (full break-in) vacuum relay and a heavy-duty Hypersil plate transformer.
    Protection Circuitry: Equipped with ALO (Automatic Lock Out), which halts amplifier operation if it detects high SWR, mistuning, or over-current on the tubes.

    Cooling: Utilizes a quiet, efficient multi-speed cooling system designed for continuous amateur duty.
