RM KL 500-24  300W with pre-amp

A high output 24 volt amplifier.

Because this is 24V it only needs a maximum of 16A to run it, the equivalent 12V one would need 32A for the same output! (guess how much a suitable dropper would be for that!).

The amplifier has variable output through a 6 position switch (from about 50W upwards) and a switchable receive pre-amplifier (not variable).

Voltage 24-28V
Current 5-16A
Input AM/FM 1-10W
Input SSB 2-20W
