Need Help Building an Audio Amplifier with D2059 Transistors

Click For Summary

Discussion Overview

The discussion centers around building an audio amplifier using D2059 transistors, with participants seeking circuit diagrams and guidance. The scope includes practical electronics assembly and design considerations for audio amplification.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses a desire to build an audio amplifier using 4 D2059 transistors and requests a simple circuit diagram due to limited electronics knowledge.
  • Another participant mentions having various MOSFET transistors but struggles to build a sound amplifier, seeking simple circuit designs for amplifiers ranging from 100 to 200 watts with specific voltage requirements.
  • A third participant compares the request for amplifier plans to asking for instructions to build a car with unrelated parts, suggesting a lack of understanding of the components involved.
  • Another participant acknowledges the D2059 transistors as medium power 100V NPN and PNP transistors in TO-220 packages, providing a link to a datasheet for further reference.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the feasibility of using the specified components for building an audio amplifier, and there are varying levels of understanding regarding the requirements and complexity of the task.

Contextual Notes

Limitations include the lack of specific knowledge about the D2059 transistors and their suitability for audio amplification, as well as the absence of detailed circuit design information in the discussion.

Who May Find This Useful

Individuals interested in audio amplifier design, electronics enthusiasts, and those seeking guidance on using specific transistors in practical applications may find this discussion relevant.

Good morning Thank you very much for being part of this forum. I have a concern. I have 4 D2059 transistors and I want to build an audio amplifier, but I don't have enough knowledge of electronics. And I have one more transistor tip117. Can anyone help me by sending a simple circuit diagram how to assemble this?
 
Engineering news on Phys.org
I also have a large number of MOSFET transistors of all kinds, but I can't build a sound amplifier with that.
I need simple schemes up to 200watt to 100wat. With normal and symmetrical sources up to 20v to 40V. It can be up to 35v too.
 
To put this in perspective, what you ask is like saying:
I have 4 wheels with tires, a steering wheel, and a radiator. Can some send me plans on how to build a car?

Btw, I didn't even look up what those part number actually are. For all I know attempting to use those parts would be the equivalent of putting square wheels on a car.
 
Welcome to PF. :smile:

Maybe try a Google Images search on mosfet audio amplifier to get some ideas...

I didn't either until just now. They are medium power 100V NPN and PNP transistors in TO-220 type packages:
