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.
