Here is a good working IntraAction Model PA-4050-8 High Power RF Power Amplifier, with 20-60MHz operating range and 50W output. Operates on 115/230v AC with included power cord.
IntraAction PA-8 Series Amplifiers can be used to increase the RF power capability of laboratory signal generators, sweep generators, frequency synthesizers, and other signal sources. The Model PA-8 Series Amplifiers can also be used to drive acousto-optic modulators, frequency shifters, deflectors, and mode lockers. It can also be used for antenna and component testing, for line drivers in signal distribution networks, and for RFI/EMI testing. The fault/interlock circuit will latch the power supply off when an open circuit condition is present at the interlock input BNC, and can be connected to the thermal switch of a high power acousto-optic device or in a normally closed interlock circuit.
