[Elecraft] KPA-1500 Power Supply Cable Size

[Bob McGraw K4TAX]

Points to consider.  A legal limit amp dissipates ~1kW of heat. Small compact amps must provide the same heat dissipation as physically large amps. Thus airflow must increase in order to cool the components in a physically small case amp.  Physically large amps have more room and slower airflow with the same cooling capacity. Slower air makes for less turbulence and equally less noise.
