Hi,
You could make the CMOY headphone amplifier. I've been using that for some time now, and I remember that when I built it, it cost me around $10, with rechargeable battery, charger and enclosure, all completed beautifully.
Tahmid.

Many thanks for the help. I am thinking that I will probably try the cmoy first. But the class A amp with the 12 V power supply might also be in my budget... I need to check with my wife. I will let you know how it goes.

jimwit, I don't know what your location is. Around here a lot of people discard old CRT monitors and old computers. You would be able to get a lot of good parts out of them, such as mosfets and bipolar transistors, capacitors, etc. The only thing you'd be left to buy would be a few resistors and the opamp if you choose to do an opamp based amp. I get a lot of good parts this way which sometimes I use for prototyping and testing ideas. Good way to save a buck.

Cannot forget about Pete Millett's Starving Student, can be made for about $35 if you scrap some kind of chassis. Hybrid design.

I started with a Cmoy along with some very efficient headphones. I think I only used about 2 - 8 mW. You don't need much power!

Don't get too outside of the box on your first build. Build something with a lot of documentation and support. AMB offers fantastic designs and boards, and kits are sold through glassjaraudio.com (I think that the mini 3 kit is around $80 for everything). if you don't want to source the parts yourself (don't known where you are in the world). Getting the parts yourself from digikey, mouser, newark, etc is a good thing to start doing though, because you begin to familiarize yourself with their catalogs, and the parts that they have available, which is great later on when you're building or repairing something that doesn't have the same detailed documentation that AMB does.

Keep in mind that if you only intend to build one amplifier, you are better off buying one, either from a builder, or a commercial product. By the time you purchase all the necessary tools to build, soldering iron, multimeter, desoldering tools, solder, solder wick, drill bits, pliers, clips, holders, etc, you will spend many times your initial figure of $50. (and if you are anything like me, you can expect to break a few things too). This is a great hobby, and I have definitely saved money over what I might have spent on similar commercial products, but it is not the cheapest way to get good sound all the time.

So, check out AMB.org. Start with a project that offers a circuit board that is well documented and supported. You can also look on the amb website for builders who don't charge much for their services and offer his products already made.

Have fun in your search!

Aaron.

You can use two 9V batteries for power.
