Headphone Amp (Chu Moy) : 10 Steps - Instructables
Headphone Amp (Chu Moy): I Wanted to make one of these for a while now, Stereo mini jack (3) Radioshack(274-0246) Digikey(CP-3513) DIP-8 IC sockets, gold contacts First step is to solder wire to all the pins of the headphone jacks,1. The tools you need for this build are nothing special. All you need is: A soldering iron Some wire strippers (or in my case a leatherman squirt)..2. The only thing i had real trouble with getting for this build was the protoboard. Being a radioshack model i found it hard to get in the uk, how..3. To start you will need to understand the board, as you will see from the images below there are two sides. One side played in copper and the oth..4. The jumpers are made from spare resistor legs (or capacitor/led legs) that are then bent and placed into the holes before being soldered on the..5. The diagram shows the layout and polarity of the capacitors in this section. i did not put the led in this step as i still need the enclosure fo..6. The purpose of this socket is to allow you to change op-amps without the need to solder, it also prevents the amp from getting hot and damaged d..7. R2 = 100 K 1/4 W metal film resistorR3 = 1 KΩ 1/4 W metal film resistor (this gives a huge gain of 11, we will change this later but for now put..8. First step is to solder wire to all the pins of the headphone jacks, about 2 inches long. once this is done we can solder up the potentiometer (..9. As you will see from the image below, all the connections for the jacks and pot are listed, take a few minutes to understand it all. the images..10. I didn't get any images of this as it is pretty straight forward, drill a hole big enough for the part to put through and well, put it through..
Op-amp Headphone Amplifier : 19 Steps (with Pictures
This is a headphone amplifier similiar to the one designed by Chu Moy. For reference, the original Chu Moy article is here while a great tutorial on building it is here.I have used a different dual operational amplifier, the RC4560, manufactured by Texas Instruments, in the TSSOP package, and chip resistors in order to make an extremely small printed circuit board assembly.1. The active device is the RC4560, which Texas Instruments claim to be suitable for, among others, Headphone amplifiers. It can work down to +/- 2..2. The circuit is the standard non-inverting amplifier with a gain of 11, with a capacitively coupled input. A small valued resistor at the output..3. The picture shows the integrated circuit and resistors. The chip is a free sample from Texas Instruments, and the resistors are all scrounged fr..4. Before etching the PCB, we need a design. Since there are a total of nine components on board I opted to use the simplest, most widely available..5. I used the salt water etch process, documented here in instructables to make the board.A small piece of double sided copper clad epoxy board was..6. The other side of the board was covered with a layer of duck tape. This side is covered with a layer of permanent marker. The markings are still..7. The places where copper is to be removed was scratched to expose the underlying copper using an awl. If you have a dremel with a pointed tool, a..8. This is how the board looks after copper removal by electrolysis, and removing the etch resist by wiping with acetone. Those lines were scored i..9. The resistors have been soldered into position, together with some links to the other side - the + 4.5 V and - 4.5 V supplies to the op amp, and..10. The chip has been soldered in. If the measurements of the pattern was correct this should sit with its leads in the middle of the pads. If the..
