Sold Out - discontinued

A single valve (EL509/519) amplifier for base use, powered directly from the mains.

Valve amplifiers tend to give a cleaner signal than their transistorised equivalent, but you do need to allow time for them to warm up and ensure that you tune them correctly.

Frequency 26-30MHz
Voltage 230V AC
Input AM/FM 1-10W
Input SSB 2-20W
Output AM/FM 100W max
Output SSB 200W max
Size 170 x 240 x 115mm

RM KLV 250  transistorised mains amplifier

A solid-state (transistor) amplifier which is powered directly from the mains.
Output can be selected high or low (approx half when on low) and there is a variable 26dB pre-amplifier.

This has the advantage over it's valve equivalent of giving instant output (no warming up) and requiring no tuning.
The disadvantage is that transistors are much less tolerant of a high swr and will blow if the swr is too high.

Frequency HF
Output SSB 240W max
Output AM/FM 120W max
Voltage 230V AC
Size 170 x 280 x 115mm
Input SSB 2-20W
Input AM/FM 1-10W
Preamplifier -10dB to +26dB

RM KLV 550  transistorised mains amplifier

A solid-state (transistor) amplifier which is powered directly from the mains.

Output power is variable in 6 stages, giving outputs from approx 50W to 300W (depending also upon input). There is a variable 26dB pre-amplifier.

The front panel also has a 13.5V outlet with a maximum current of 3A.  This is suitable for powering a low power radio or various low power accessories.

This has the advantage over it's valve equivalent of giving instant output (no warming up) and requiring no tuning.
The disadvantage is that transistors are much less tolerant of a high swr and will blow if the swr is too high.

Frequency HF
Voltage 230V AC
Input AM/FM 1-10W
Input SSB 2-20W
Output AM/FM 300W max
Output SSB 600W max
Size 310 x 240 x 140mm
Preamp -10dB to +26dB
