Need Help Building an Audio Amplifier with D2059 Transistors

AI Thread Summary
A forum user seeks assistance in building an audio amplifier using four D2059 transistors and a TIP117 transistor, expressing a lack of electronics knowledge. They request simple circuit diagrams for amplifiers ranging from 100 to 200 watts, compatible with power supplies of 20 to 40 volts. Other participants suggest researching existing designs, particularly using MOSFETs, and provide insights into the specifications of the D2059 transistors as medium power NPN and PNP types. The conversation highlights the complexity of the request, comparing it to building a car from basic parts. Overall, the user is encouraged to explore available resources for amplifier designs.

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:

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
