I have been building and DIYing for 45 years now and happily will never stop. This tube headphone amp is from a thread in the Form. The sound is better than my ears have ever heard so I will be keeping this one for my retirement entertainment should such a time ever come. Wink It has worked from day one and continues to please me every time it is turned on. To spite it’s small size the parts are quite easily accessed. I over built most components so it will outlast me I fear.
Audio circuits to build
June The road to making your own DIY audiophile passive preamp can be long or short. Both my parents were hands-on makers, doers and fixers as long back as I can remember. My first car at 16 needed a new fender. House really needed a new kitchen but too stubborn cheap? The kitchen took over a year to get done.
** UPDATES Feb I have upgraded literally EVERYTHING since July I kept with the same general system composition; in many cases simply moving to newer model years and/or the next model(s) up. I did change from all Rogue Audio electronics to VAC & ARC for phono stage & preamp — yes, I have to admit that was the right move for me to finally make.
DSD audio, easy to use Dislikes: And it is so easy to use that a novice can be up and running in a few hours, dubbing that original Sgt. It includes a phono input making it a perfect solution for high-resolution, vinyl archiving. We have discovered a nearly perfect audio device for dubbing your LPs to the hi-res digital format of your choice: The front panel of the simple, sleek, stylish box includes a stereo headphone jack and a large volume pot that is encircled by a glowing LED ring.
There is no specific AudioGate4 app for Android users, even though Android is much more hi-res capable than IOS when it comes to ultra high-res playback. Fortunately, there is a wide selection of hi-res-capable playback app options for Android including: The TN was switched to phono input via the AudioGate4 software. Although the phono equalizer curve is applied in the digital domain, it cannot be changed after a recording is made.
So if you are unsure of the curve, you should record with this setting set to Off.

The big difference is the outboard power supply for the E-Glo, whereas the E-Glo S is one chassis with an 18V power adaptor. While the MM gain is 45 dB. Each selection is illuminated with a small LED indicator on the faceplate but you may have to squint a little bit to see them. The tubes are also wrapped in an EAT cooling damper. The E-Glo S is not a stackable component, those delicate tubes and all.
All preamp models now feature toggling between the Strain Gauge function and single or (multiple) line inputs for maximum hookup flexibility to your equipment Low tracking forces with extreme precision.

Phono Turntable Preamp
No “ocean noise,” but there is a hum. Thankfully, it’s beyond the level of peak listening volume, so it’s not much of a problem right now. I suspect it’s caused by DC offset on the outputs that are bedeviling me something fierce.
– Cables / Hookup wires – Displays – Enclosures – Magnets – Nuts & Bolts – Peltier Cooler Heater – PIR – Sensors Adds phono input and microphone input to amplifier; the preamp used on the magnetic pickup must “de-emphasize” the boost in the highs.
Page 1 Page 2 It seems like, every few years, Krell goes through a major cosmetic and sometimes engineering revamp. Visually, the song always seems to be the same: The new Illusion II digital preamp embodies the same industrial design ideas as the new iBias amplifiers: It’s still macho, though. It’s a straightforward high-end digital preamp–i. If it seems like something’s missing, it is: This isn’t a big deal; you just need to add a USB-to-coax converter, which I’ll discuss in the Hookup section below.
The Illusion II also has four stereo analog inputs:

Apr 16, · We know your phono preamp works, and the line input on the Onkyo works. This is not an impedance problem as the output impedance of the phono preamp is lower than the input impedance of a line input. I have to feel the cable is the problem.

Beyond staggering, an extra zero after staggering and I honestly believe that the Citation blows them all away. If you are in the market for an amp, talk to Jim McShane. His interconnects start at about 6 times what our line tops out at, but he was very interested in our design and wanted a good listen.

What devices do I have to purchase? My turntable connects directly into my receiver!! Nothing else is needed!!! Unlike other line level equipment like a cassette recorder or CD player, the output from a phono cartridge must be re-equalized via a special circuit. Thus to connect your turntable, you’ll need to purchase a phono preamp. Plug the output leads from your turntable into the input on the phono preamp and the output from the phono preamp into any of the available line level inputs on your receiver e.
You’ll also need an extra set of interconnects to go between the phono pre and your receiver. Of course if your receiver has a phono input, skip the above and just plug the turntable into the inputs marked “phono. I connected my cables from the turntable into the cd slot and it works fine. The signal encoded on vinal is altered from flat according to RIAA specs. In addition to boosting the signal, the phono preamp re-equalizes the recorded signal to produce a “flat” frequency response.
I guess if I was playing more modern records, I would notice a difference!!!
Signature SG Systems Preamplifier
Parasound Parasound is best known for its high-value, high-end audio components, especially the top-tier models designed by John Curl. The man has had a long relationship with Parasound, but before that he crafted the legendary Vendetta phono preamplifier, worked for the Mark Levinson company and designed concert sound systems for the Grateful Dead. This amplifier pumps out watts per channel for 8-ohm speakers, watts per channel for 4-ohm speakers, and it’s based on John Curl’s designs used in Parasound’s separate power amplifiers.
Up front, the solid aluminum volume knob sits next to an easy-to-read display that shows volume level from , and I like that you can program a default turn-on volume level.
I have previously tried to hook it up by taking the phonograph and plunging it into the input channel of the equalizer and taking the output of the equalizer and running it to the the Phono 1 of the amplifier.
Having read the document and looked at figure 3 You don’t have to leave the chassis ungro Gamut D Grounding Question I would snip the ground going from the RCA jack to the chassis. Then connect your ohm Then connect your ohm meter between chassis ground and the neg tab of the RCA jacks. You should have continuity.
Then connected the ohm meter between chassis ground and the neg tab of the RCA jacks. And if they are, lifting the ground at one end of 1 RCA will still let the common ground on the ot Ground Loop Problem Break this connection and the hum will go away. BTW, you said “The pre is battery powered What’s wrong with my Quad ?

Sep 15, · Best Answer: You can only do this if your receiver has a “phono” input. You can not connect it to an “Aux” or “CD” input. The turntable will require a phono preamp Status: Resolved.
Even if it’s working, you can make it sound better than it ever sounded. You can feel the great feeling of accomplishment that comes from building a kit You begin with a collection of quality parts, and end with something that sounds great, looks great, and works great. And you built it! The Dynaco Stereo Power Amp was revolutionary when it came out in the mid ‘s. It had some problems, though, mostly related to under-biasing of the output stage. The result was the cross-over distortion that came to be the unpleasant hallmark of “transistor” sound.
Forty years of progress later, we can do a lot better. With our kit, you recycle and reuse the highest quality, timeless parts of the Stereo , and replace the parts, e. The updated amplifier modules have been improved. We’ve included some but not all of the improvements of the GT amplifier modules into the TCK modules. The improved version is called Rev B. Added components give quiet turn-off even when paired with C12 Upgrade kits the original design required the quiet turn-off mod to be retro-fit into the board Value changes slightly increase the maximum output power prior to clipping.

Solid-state Bi-Wire Ideas Most solid-state power amplifiers are far cheaper than most tube power amplifiers. There, however, exceptions, as massive solid-state class-A power amplifiers cost a bundle. One idea that has danced in my mind for a long time now is that I would like to force a chip amplifier, such as the LM , into class-A mode More amazingly, DACs are getting better, almost monthly; and high-res digital music files can be bought and downloaded online.
Features: Designed to convert the signal from your magnetic cartridge on a turntable to an AUX input located on an amplifier. The normally weak turntable signal will be amplified to be compatible with the AUX input (mv). The AP can be used to convert most AUX inputs normally found on audio amplifiers and mini sound systems.

Featured Post By popular request really, I got quite a few emails about this! An internal preamplifier is an excellent idea since many modern receivers do not feature a dedicated phono input anymore.
After doing a bit of research about modern RIAA preamp designs I settled for the LM operational amplifier, which is an optimized low-noise design for audio applications. There is really no need to re-invent the wheel when it comes to RIAA preamps, this has been figured out long ago.
