PAiA - TubeHead Vacuum Tube Preamps. If you love vacuum tubes, these pre-amps have your name on them. The TubeHead is a low-cost, two-channel vacuum tube pre-amplifier with a twist; it's designed to be adjustable from crisp, solid-state transparency to an exaggerated caricature of tube amp warmth. In between these extremes, you'll find tonal coloring options that you've never had before and sounds that mimic every tube amp you ever heard. This circuit is so versatile that you may use it in place of compressors, limiters and sustainers even though, technically, it is none of these.
Tube Sound? In sound systems from the golden age every link in the chain had distinct "squashing" non-linearities. How Tubes work "Starving" tubes with low plate voltages and currents produces a caricature of tube amp warmth. Custom cases in the Builder's Hall of Fame.

Almanac on contemporary instruments. En_tpa6120a2. Introduction Because I wasn't satisfied with behaviour of LME49600 based amplifier specially at power-up I designed headphone amplifier with chip TPA6120A2. Circuit is almost same like amplifier which I designed in a past. I was satisfied with a circuit that I used them again. Circuit description Circuit correspond to recommended datasheet circuit.
Unlike past circuit are changed resistors R2 to R5 from a value 1k to 820 ohms for better stability. Schematics diagram Assembling First I assembled IO1 amplifier circuit.

Pittsburgh Modular Move  Limited Eurorack Case – Nerd Audio. The Pittsburgh Modular Move  Limited is a beautiful and rugged eurorack case with power supply, designed to safely run up to 104hp of synth modules. Handbuilt in Pittsburgh using select Ukrainian Birch Ply, the Move  Limited case celebrates the classic pairing of synthesizers with beautiful hardwood. Each case has been constructed and stained by our craftsmen to emphasize its unique beauty. The strength of the Ukrainian Birch Ply allows the Move  Limited to stand up the the most rigorous road use. Designers of skateboards, hockey sticks, furniture, and countless other products demanding a strong yet lightweight wood have chosen Birch Ply for years because of its unique combination of strength, weight, and durability. Each case includes a removable lid. A complete set of nickel plated steel corners is also included.

Inveterate meddling #377: Quick notes on using 3-Pin Voltage regulators or at least - some things the application notes don't make obvious Many of the tweaks and mods on this site and elsewhere are based around providing 'cleaner' power supplies to the many separate elements which comprise audio systems.
In essence, this works because a 'clean' supply is one which i) contributes as little excess noise as possible and ii) has a very low output impedance, so that it interacts with the powered circuit as little as possible by forming a 'perfect' source and sink for all currents. The backbone of clean supplies is voltage regulation, and the workhorse of cheap and easy regulation is the humble three-pin regulator... In a nutshell, the output voltage adjustment works like this: the 317 actually only regulates the 1.250v across any resistor placed between VOUT and VADJpins (R1). Actually, it's a bit more interesting than that. Now look at this graph: On to Part Two... © 2006 the twisted pair. Studio | Clicks & Clocks.

How to build a Solid State Tesla Coil | SSTC 2 by Loneoceans Labs. How to build a Solid State Tesla Coil If you are here to learn how to build a SSTC, you have come to the right place! Welcome! The design and construction a Solid State Tesla Coil (a Tesla Coil powered by Transistors instead of a spark gap) is not a trivial task. However, the basic mechanism and workings of a SSTC are not too complicated. The main challenge in building a SSTC lies with the fact that the builder should have a good understanding & experience with electronics, and have some test equipment (oscilloscope is required) for debugging, which many beginners may not have. There are also several subtle but important things to take note of which are usually difficult to find information about. Unlike spark-gap or vacuum tube Tesla Coils, building an SSTC is not as straightforward as copying a schematic. I will document this guide through the construction of a very simple Solid State Tesla Coil - SSTC 2 - which I have designed to be simple, compact, and produces good results. 1.
Toroid. Hc6ssch. Digital Remotes. The DR (digital remote) models are designed to control HAL in various ways: volume setting, preset recall, source selection, or reset / toggle system states. The DR1, DR2, DR3 and DR6 allow customizing labels for end users, while the DR4 and DR5 offer incorporating custom switches and other devices to control HAL. Status indicators on each HAL or EXP host, and in Halogen software, report wiring status to assist troubleshooting. All are hot-swappable with homerun connections using shielded CAT 5e (or better) cable. DRs get their control functions from the HAL port they are connected to, which eliminates individual addressing. DRs connect to either a DR port (brown) or a RAD port (blue) on the rear of a HAL or EXP. While the RADs have a 150 meter (500 foot) maximum distance, any DR (except the DR6) can run up to 300 meters (1,000 feet) away from its HAL.
80017A VCF/VCA Teardown | Obsoletetechnology. After I replaced the defective VCF/VCA IC on my Juno 106, I always felt the urge to take a look into this hybrid IC, in order see what components Roland has been using for the filter and the VCA. I tried several ways to remove the enveloping compound covering the chip. First I tried with a sharp knife to break of the lacquer which didn’t work out and is pretty dangerous too, then I tried dissolving it with paint thinner without any effect at all. Finally, I tried out some Acetone, where I left the component in over night, and this seemed to penetrate into the compound, making it flexible and eventually coming off by gently poking around with a sharp screwdriver. Curiously, neither the SMD IC’s nor the fiberglass PCB got damaged by this process and I was left with a nicely stripped down board. Inside the 80017A VCF/VCA The resistors on the board are made via a printing process, thus not replaceable, the SMD’s could be replaced but are long obsolete.

Part 1: MIDI Hardware The MIDI 1.0 Specification states: The interface operates at 31.25 (+/- 1%) Kbaud, asynchronous, with a start bit, 8 data bits (D0 to D7), and a stop bit.
This makes a total of 10 bits for a period of 320 microseconds per serial byte. Circuit: 5mA current loop type. Logical 0 is current ON. One output shall drive one and only one input. Connectors: DIN 5 pin (180 degree) female panel mount receptacle. Within a year of its introduction in 1983 MIDI was adopted as standard by the entire electronic musical instrument industry worldwide with a very high degree of compatibility.
The reason behind the overwhelming success was that the standard was very carefully researched before being revealed publicly. There are many ways of implementing and applying MIDI depending what market or application is being targeted. Since the beginning of 1996 all equipment sold in Europe must conform to CE EMC requirements and North America already had similar FCC regulations.
Hardware. June 2012 | La Révolution Deux. Power Scaling (a London Power trademark) and VVR, which stands for Variable Voltage Regulator, (Dana Hall of Hall Amplification's version of Power Scaling) are currently two of the hottest topic's in the Guitar Amp world. Both are methods which allow you to scale back the voltages within your amplifier to attenuate the overall volume without having to use a cumbersome purpose built attenuator between the amplifier's output transformer and speaker or rely on a simple "Master Volume" control which dials out the all important power tube clipping. Voltage scaling is said to allow you to maintain "that" tone you get from running a tube amp flat out with all the volume controls turned up to the max but also allow you to maintain your relationships with neighbours/children and/or spouses without having to resort to playing your guitar in an underground bunker.
Best of all this technology is compatible with 99% of amps below 50W! Firstly; SAFETY! "Not at all! So how does it work? Ordering Information. December 2015 Shut Down There's a whole bunch of jobs to do around my house - rewiring, decorating and just generally catching up with stuff - so I'm taking a break from Oakley related work over the whole of December and the New Year period. As such: I shall not be shipping any orders from now until 4th January 2016. I will check my work e-mail and I will be able to take orders - although perhaps not as speedily as I normally do. However, any orders placed over this period will not be posted until after the New Year.
