I want to drive a Low "Q" Antenna, about 50 Ohms of Resistance.
The frequency is 200 KiloHertz.
I wish to purchase the PA (New or Used). A Warrantee is required.

200 kHz is allocated to aeronautical mobile and aeronautical navigation in the US. If you're licensed to operate there check with aviation equipment supply companies. If you're not authorized to transmit there expect a very stiff fine when the FCC comes down on you.

You need an oscillator that operates at that frequency, such as a signal generator. Very easy to find. Then a power amplifier that can operate at that frequency. Most good audio amps will work at that frequency, but check the specs first. You should be able to find 200 watt amps easily. But first you need to state what the voltage and power is before you can even look for an amp or circuit. EDIT: the voltage DOES matter, (or the impedance) you can't start a design or pick a model without that information.

Why high current and low voltage? At 50 ohms impedance you must have a very large transmission line to handle the current.
