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).

The KL 405 is a 180Wmax 12V linear amplifier for use on the 10m Amateur Band, (or other HF bands with the use of a suitable Low Pass Filter). It requires a drive power of 1 to 10W in all modes.

The KL 405 features a six position output power selector via a front panel control and a RX preamplifier with electronic switching, which can be activated via a switch on the front panel. The V version comes with a 80mm heatsink mounted fan.

A high power broadband amplifier with variable output power and switchable pre-amplifier (not variable), this is a replacement for the KL500.

The features are all the same as the KL405, but the amplifier uses Mosfet transistors.

The output can be adjusted in 6 stages, from approximately 60W minimum to 250W maximum (AM/FM).

Note: new stock is now in a black case.
