I decided it was time to build a preamp to aid in testing power amps and for other uses on the bench. If you build one for audio use, I'd recommend adding 100 ohm output series resistors to keep the amp stable when driving capacitive loads such as shielded cable runs.

Disclaimer: These transformers are around $2 and the frequency range is 300Hz to 10,000Hz. This video illustrates the concept of using transformers to passively increase the voltage output of a device like an Ipod. If your application needs a frequency range of 10Hz to something over 18KHz, then you need to purchase Sowter or Jensen audio transformers ($80 a piece and two are required). This passive preamp doubles the 2.8V audio output signal to 5-6 volts which is typically required for any AUX input on a car or most inputs that state CD input. An IPOD or IPhone is designed for 2.8V to save battery power and to drive the typical IPOD ear buds. However, to drive a 5volt input, you have to turn the IPOD volume ALL THE WAY UP. When you forget to lower the volume before plugging back in your ear buds, well, you get an unpleasantly LOUD VOLUME BLAST. This device will allow you to switch between an ear bud and a AUX (or CD) input device using only half the volume of the IPOD.

Preamps used to be a necessity in any serious high-end audio system. With the advent of digital audio, this must-have category of product started fading into the shadows as more and more customers went directly from DACs to amps. Was that a good move? Are preamps necessary for the best performance? Have a question for Paul? Head to http://www.psaudio.com/ask-paul/

Remember back when a dollar cost a nickle, terrorists were called "Commies," and pop was called "Rock N' Roll?" Golden Age does. And they'll help you remember what that time sounded like with the help of the Golden Age Project Pre73 vintage-style microphone preamplifier. Owen's a bit too young yet to know what the PreCD world sounded like, but he likes the sound of the Pre73. Inspired by the sound and circuit design of the Neve 1073 solid state mic preamp, the Golden Age Pre73 eschews modern IC chip design in favor of old-school discrete component design for natural, vintage warmth and punch. Of course, all this talk of audio quality is subjective, so why don't you stop reading and watch the video already?

Welcome back to ProGuitarShop and ToneReport.com. Today, we've stepped into the web of the Black Widow MGP-1A. The MGP-1A is the world's first all-analog tube powered modeling preamplifier. Unlike every other modeling preamp on the market, the MGP-1A relies on Black Widow's proprietary VEnuM technology that uses real tubes and highly-refined switching circuits to reconfigure components in the signal path on the fly, controlling delicate elements such as breakup characteristics and harmonic generation. Black Widow designed the MGP-1A to perfectly emulate a variety of different classic preamp sounds in tandem with enhancing the touch sensitivity and dramatically reducing the noise floor. 18 all-tube preamp circuits are available, with three channels of three amps apiece and a full complement of EQ controls. The Clean channel features a '59 Bassman, a Marshall JTM-45 and a Vox AC-30. The Crunch channel serves up models of the Mesa Boogie Mark IV, Marshall JCM800, and a classic Orange Graphic MKII. Finally, the Drive Channel gives you models of the Mesa Dual Rectifier, Marshall JCM900 SL-X and the Diezel Herbert. Within each channel, several switches help further configure the raw tone, offering mods on each circuit made famous by Bogner, Engl, and several others. Across all channels, not a single one or zero permeates the signal path, ensuring that electrons flow through the preamp from start to finish. The MGP-1A also features full MIDI control, so you can swap parts on stage with a foot controller or from the chair at your DAW. Every component within the MGP-1A is painstakingly curated, from the four Tung-Sol 12AX7s down to quality resistors and audiophile-grade capacitors. These passive components are reinforced with a number of enhancements, from super-thick silver-plated PCBs to heavy duty switches and a solid steel chassis.

This is Part 1 of a two-part video series discussing (in very basic language) virtually all aspects of tube amplifier (passive) tone controls. Topics covered: 1.) The differences between active and passive tone controls 2.) Different locations for tone controls within the amp circuit, including benefits and drawbacks of each 3.) The use of a cathode follower to match impedance between circuit and tone stack 4.) Capacitor theory regarding AC/DC response and frequency passage 5.) High Pass and Low Pass Filters....design and function. This series is in response to numerous requests and is best suited for those who seek a basic understanding of amplifier design and function. The tone is conversational and, as usual, relies upon simple language, analogies, and explanations. In addition, Rusty makes a couple of appearances and his nemesis, the Cat, is offered his job behind the camera......with somewhat predictable results :) If you enjoy videos featuring classic vintage tube amplifiers, jukeboxes, home-built electronic marvels, and basic, understandable technical presentations, then please subscribe to my channel.

LINKS TO AUDIO FILTER VIDEOS IN THIS TEXTBOX. Do Germanium transistors and Silicon transistor each have their own "sound color"? In this video I test the difference between a AC 187 (NPN Germanium) and a BC 547 (NPN Silicon) in an audio pre amplifier (approx. 0,3 % distortion). Take your own conclusions about possible sound "coloring" and/or do your own tests with different NPN Silicon and Germanium transistors with this circuit. Much more audio in my book "Schematics 2, audio amplifiers and loudspeaker boxes" (author Ko Tilman) on the Lulu website. By the way: I am almost sure that a germanium transistor audio amplifier has another sound color, compared to a silicon transistor amplifier. This is based on my experience and listening. The question is: which sound do you like? And/or: it is possible to give a Silicon amplifier a sound (with tone control) that resembles the sound of an (old) Germanium audio amplifier.

It's amazing what a little disk can do ... when it's layered with piezoelectric crystals. Piezo disks are impressively sensitive to vibration and can easily be adapted to work as a contact microphones. The trick is the preamp - a basic circuit used to match the piezo's signal to levels compatible with modern audio gear inputs. The resulting piezo/preamp combo can be used for electrifying an acoustic guitar or simply exploring the lesser-heard world of small sound around us.

QUESTIONS Where are the camera reviews? Apologies to the people looking for new camera reviews - due to a run of ill health and bad weather I've been unable to get out and shoot the footage I need to finish off a couple of these videos - hopefully I'll get them done soon. Where is the Minidisc video? Back in January on the DAT video I mentioned that MD was going to be the subject of a future video. These format videos take me months to assemble so the MD one should be along *sometime later this year*...probably within a couple of months. Where are the puppets? I try to make one of the muppet outros a month, but they don't fit in with every video, so I wait until a suitable subject comes along that could benefit from their input. Where are the Outro Videos? In this playlist https://www.youtube.com/playlist?list=PLN2yCnHTG_6rlyYFpwUX2u0m_HVHpHO0F What's that black turntable? The black turntable I used in the video is a Pro-ject RPM 1.3 Genie (It’s my old turntable and I don’t recommend it. Here's my 'review' I really don't like it...it's been in the attic for a couple of years. It's too flimsy, every part on it moves whether it's supposed to or not, it cost me too much, is susceptible to picking up hum, it has a stupid anti-skating weight hanging on a piece of string that falls off all the time, the belt gets knocked off easily and is a hassle to put back on. I was so happy to replace it with my retro automatic Sansui XR-Q7, one of the best automatic direct drive turntables ever made and it cost me less than the Pro-ject RPM 1.3 Genie. I only kept this abomination in the off-chance that I might be able to use it in a future video. It does look good though - I'll give it that. Why not use classical music if you want to play something that's copyright free? Because it's not necessarily copyright free. Ok so Mozart and Beethoven are dead...but if an orchestra gets together in the Albert Hall and together with recording engineers record some of their music and put it out on a CD then that *recording* is copyright. They spent considerable money, time and effort to make that, so deserve to earn some money for it. Mozart might get jack-all but somebody who spent twenty years learning to play the violin and the record company and engineers etc etc all need to get paid. I once tried to use a section of Ode to joy - Beethoven symphony No. 9 and the video was auto-flagged for copyright infringement within seconds of being uploaded.

The VT-737sp brings its magic touch to everything in your studio. Run your dullest, most sterile mic through the VT-737sp and you'll be amazed at how warm and sweet it sounds. This 2-rackspace combo brings a new standard to high-end audio, taking your sound to places you never thought possible and giving you precise creative control. The VT-737 will energize your recordings! Avalon VT-737sp Channel Strip at a Glance: Class A preamp design with three input selections Opto-compressor with minimum signal path Sweepable EQ and hardwired bypass Class A preamp design with three input selections The VT-737sp has three input selections: First, it features a higher-performance microphone input transformer with 48-volt phantom selection. Second, the VT-737sp offers an instrument DI high-source input with a jack located on front panel. Finally, the VT-737sp includes a balanced line input with discrete high-level Class A circuitry. The Class A preamplifier utilizes two cascaded, dual vacuum tube triodes configured with minimum negative feedback. A high-gain switch boosts the overall gain of the preamplifier. The four high-quality tubes are configured as singled-ended anode coupled followers. A passive/variable high-pass filter and hardwired relay bypass completes the VT-737sp's input signal conditioning. A phase reverse relay is available on all three inputs. Opto-compressor with minimum signal path The VT-737sp's opto-compressor features a minimum signal path design with twin Class A vacuum tube triodes for gain matching. The optical attenuator acts as a simple passive level controller. Full dynamic control from soft compression to hard- knee limiting can be achieved with threshold, ratio-compression, attack and release controls plus gain reduction selection on the large VU meter. Special spectral control including de-ess is available with the dual sweep mid EQ to side-chain switch. The VT-737sp's EQ section can be flipped pre or post the opto-compressor via a front-panel switch for alternate effects and tone shaping. Two VT-737sps can be linked via a rear panel link cable for stereo tracking. The compressor bypass is a sealed silver relay for the most direct signal path. Sweepable EQ and hardwired bypass The VT-737sp equalizer utilizes 100% discrete, Class A-high-voltage transistors for optimum sonic performance. The high- and low-frequency bands provide the smooth characteristics of an all passive design, while the dual mid bands include variable frequency and switched Q-width selection. The enhanced range of the VT-737sp's mid bands is extended into the high and low bands by the use of X10 frequency multipliers. The bypass switch incorporates a sealed silver relay for the most direct signal path. When the EQ to sidechain is engaged, the high-low EQ remains in the audio path for "tone enhancement." The output level control provides a variable control of the overall signal path. The output amplifier utilizes another dual triode vacuum tube driving a 100% discrete, Class A, high-current, balanced and DC coupled low noise output amplifier.
