This is the circuit design of 1000W stereo audio amplifier. It is a very good design to assemble, easy to build from your board to the acquisition of components, the output transistors are the COMPLEMENTAR 2SC5200 and 2SA1943 relatively cheap and with very good result. The Linear Amp Pioneer 572 utilises four x 572B valves in fully neutralised grounded grid configuration and will produce up to 1000 Watts output with 100W of drive. • Full coverage from 1.8-30 MHz incl WARC Bands • Metering of HT Voltage & True Forward Power Output • Antenna Changeover PCB Incorporating Forward Power Metering Circuitry

The component of preference is a choke - in this instance, an RF Choke. By placing an RF Choke in series with the Plate/B+ circuit, we effectively permit the DC component to pass, but restrict the AC component (remember that RF is simply high frequency AC). Our final task is to extract the AC component. RF power amplifiers are what you need in your circuit design to transform a low-power radio-frequency signal into a higher power signal. Whether you want MMIC wideband amplifiers or high power amplifiers, Future Electronics stocks an exclusive collection of RF power amplifiers from industry-leading manufacturers to choose from.

Circuit description The amplifier is a class AB1 grid-driven design. The input circuit is a simple pi-section low-pass filter that cuts off around 30 MHz. It uses the input capacity of the tube as its output capacitor, thus canceling the effect of this capacity on the higher bands, without needing to be switched in and out.
The fan in the amp is controlled by a 3W rheostat to quiet things down a bit when you don't need so much air flow. (See schematic.) Next we come to the all important LC input tuning circuit for the amp. I have had the advise from other amplifier builders tell me to run away from that design.
