300 Watt Subwoofer Amplifier Circuit Diagram

Before the new hifi.

300 watt subwoofer amplifier circuit diagram.

350 watt studio amplifier circuit mjl21193 mjl21194. Description this is an amplifier circuit that is formed from a transistor amplifier miraculous. Where continuous high power is required another 4 output transistors are recommended wired in the same way as q9 q10 q11 and q12 and using 0 33 ohm emitter resistors. Driver transistors are mje15034 npn and mje15035 pnp.

This is a low cost 150 watt amplifier circuit with diagram and schematic design using two darlington power transistors tip 142 and tip 147. We are using the hifi year book as we have the whole set 1956 1981. As shown in the diagram the specified power supply does not need to be a complex stabilized but must be adequately filtered using high value filter capacitors. Hello friends i made last year i thought i d start by modifying my work 2 1.

It was originally intended for light intermittent duty suitable for an equalised subwoofer system for example using the elf principle see the project page for the info on this circuit. Driver transistors are mje15034 npn and mje15035 pnp. The output devices are mjl4281a npn and mjl4302a pnp and feature high bandwidth excellent soa safe operating area high linearity and high gain. This circuit is used in the speaker subwoof.

With upright construction the module is gifted of tall quality performance and is rated to 300 watts into a 4 ohm load depending on power supply.
