12 Volt
All the amplifiers listed below are for use on a 12V supply.
If you require one for use in a truck, please ensure you either have a large enough voltage dropper or choose one of our 24V amplifiers.
The output power quoted for SSB is maximum PEP Power.

Zetagi B300p  200W amplifier with preamp

A high power amplifier with variable output power and switchable pre-amplifier (not variable).

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

In practice we usually find these amps give a maximum output of about 150W FM and 300W PEP SSB.

RM KL35  35W amplifier

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.

RM KL 400  200W amplifier with pre-amp

A high power broadband amplifier with variable output power and switchable pre-amplifier (not variable).

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

Equivalent to the Zetagi B300p, but this amplifier gives a higher output (the Zetagi seems to struggle to make 150W).
