Tilting gradually decreases as the frequency increases and beyond about Hz the square wave response is excellent up to 20kHz irf610 is the limit irf610 my signal generator. The amp worked well between 10 and 20VDC, but seemed to work best at 13V and up.
You will want to check and reset the bias a few times in the first irf610 hours as it will drift while everything settles in. For that reason, you will need to use a regulated power irf610.
IRF610, SiHF610 product information
You will want to stay away from IRF or IRF types commonly found in power supplies as there will irf610 terrible roll-off of the highs. Plain RCA jacks are used for input source. There are a couple of items to note. The smaller heat sinks are about 1. This makes for a ultra irf610 power supply which is necessary irf610 this irf610 circuit. The photos below show irf610 second of these amplifiers that I built. I checked the sine wave response and as expected, the results were good across 20Hz to 20kHz the limits of my function generator.
The headphone amplifier was built into the enclosure from some irf610 of old Dolby processor s that I had to modify irf610. Fortunately I had a dead Plextor external CD-ROM kicking around that irf610 make for the perfect enclosure and blend in well on my desk.
Also, a simple single-ended circuit like this will have no power supply ripple rejection and thus any noise in the power supply is going to go right through amplifier.
The top trace green is the input waveform and the bottom trace yellow is the output. Suitable irf610 regulated wall wart power supplies can be irf610 from Irf610 Shack.
For irf610 power supply I am using is a 20VDC power supply from an older laptop. A FET krf610 circuit will be able to supply high current, but the voltage gain will be less than one. If you compare the input voltage to the output voltage you will see than the gain of the circuit is about 0. I only used parts that I had irf610 hand and you can see that I did not use any boutique parts.
The final touches were to epoxy irf610 CD-ROM faceplate to an aluminum plate irf610 put the enclosure back irf610. I even prefer the irf61 compared to the built-in integrated headphone amp on my NAD C preamp. The headphone amplifier was first tested smoke test using a irf610 power supply at very low voltage. Last update 17 February This amplifier will delivery plenty irf610 current to drive more demainding headphone types.
The heat sinks were salvaged from various dead components. Irf610 a simple irf610 of a common LM voltage regulator it is configured as a very accurate CCS set to draw mA. You can use carbon resistors, but I suggest you use metal film, particularly for the CCS due to their superior temperature irf610 over carbon.
Some may prefer to use irf610 quality irrf610 and bypass irf610 and that irf610 improve the irf610. In this instance I had plenty of irf610 irc610, but the sound card just irt610 out of gas with good headphones.

Plain but matched metal film irf610, 1uF mylar irf601 cap and 0. Since music is comprised primarily of sine waves this is not a problem as the sine irf610 response was fine across the audible range.
Created 30 June With a regulated irf610 there was no irf610 hum. Not thrilled with how a computer soundcard drove my 32 ohm Grado Irf610 headphones, I decided to build irc610 a desktop headphone amplifier for the office.
irf610 That was not the case ifr610 an unregulated supply. Since an mp3 player or computer will be used to control the volume, there is no potentiometer on the amplifier. As you irf610 see in the Irf610 trace, the square wave response is slightly tilted but stable. My signal generator is not great and that is reflected in the quality of the input waves.
Irf610 are two screen shots of the square wave response at Hz and Hz.
