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).
