12 Volt

A small amplifier for AM/FM only - can not be used on SSB.

Although the amplifier does not have a switch on it, it does have a built-in relay so that you can switch it on/off by putting a switch in the power cable. This allows you to hide the amp away.

A compact amplifier with on/off switch, suitable for use on FM, AM and SSB.

Relay switched, which minimises insertion loss, and can be bypassed using the on/off switch on the front of the amp.

Selectable for AM/FM or SSB.

Compact mobile amplifer with on/off switch.

Mosfet amplifier with maximum output of 100W  (typical output 80W).

Compact mobile amplifier with switchable pre-amplifier.

Mosfet transistors.

Neither the output nor the pre-amp gain are variable.

Compact mobile amplifier with switchable pre-amplifier.

Neither the output nor the pre-amp gain are variable.

A high power broadband amplifier with fixed output power.

The output is a maximum 150W AM/FM and 300W PEP on SSB).

A high power broadband amplifier with variable output power and switchable pre-amplifier (not variable), this is a replacement for the KL400 (RM351p).

The features are all the same as the KL400, but the amplifier uses new transistors, has an updated look to it, and the power cable connection is improved on the rear.

The output can be adjusted in 6 stages, from approximately 50W minimum to 200W maximum (AM/FM).
