The amplifier circuit is very least expensive and cans be powered from twenty four to 32 V/5A twin power supply. you must do that circuit. Its operating great. because four transistors (2 x 2n3055 and mj 2955) on the final amplifier can of some very hot then add the aluminum finned cooler and also the fan so the transistor is not too high temperatures.

The transistors are 2SC3858 (NPN) and 2SA1494 (PNP), and have high bandwidth, wonderful safe operating space, high linearity and high gain. Driver transistors are 2SC5200 (NPN) and 2SA1943 (PNP). All devices are rated at 230V, with the facility transistors having a 150W dissipation and also the drivers are 50W.
This circuit describes an amplifier, power offer and tests procedures that are all inherently dangerous. Nothing described during this article ought to even be thought-about unless you're totally experienced, grasp specifically what you're doing, and are willing to require full 100% responsibility for what you are doing. There are aspects of the look which will need analysis, fault-finding and/or modification.
