Mini Guitar/Bass Amplifier


Output power: 6W into 4 Ohm load, FET input stage - Passive Tone Control


Tiny, portable Guitar Amplifiers are useful for practice on the go and in bedroom/living room environment. Usually, they can be battery powered and feature a headphone output. This project is formed by an FET input circuitry, featuring a High/Low sensitivity switch, followed by a passive Tone Control circuit suitable to Guitar or Bass. After the Volume control, a 6W IC power amplifier follows, powered by a 12-14V dc external supply Adaptor or from batteries, and driving a 4 Ohm 10 or 13cm (4"/5") diameter car loudspeaker. Private listening by means of headphones is also possible.

Acura Integra EMS P/N 30-1060 Installation Instructions

The EMS is a “stand-alone”, which completely replaces the factory ECU and features unique plug and play technology. There is no need to modify the factory wiring harness and in most cases the vehicle may be returned to stock in a matter of minutes. The AEMPro software is configured to work with the factory sensors and equipment, so there is no need for expensive or hard to find sensors, making replacements and repairs as simple as with any stock vehicle. For stock and slightly modified vehicles, the AEMPro software can be programmed with base parameters, providing a solid starting point for beginner tuning. For more heavily modified cars, the EMS has many spare inputs and outputs allowing the elimination of add-on rev-limiters, boost controllers, nitrous controllers, fuel computers, etc.


While the base map may be a good starting point and will save considerable time and money, it will not replace the need to tune the specific application. AEM start-up maps are tuned conservatively and are not intended to be driven aggressively. Ignoring this can and will damage your engine.
If the 30-1060U EMS was purchased, the stock O2 #1 sensor will not be used and should be replaced with the supplied AEM sensor. The 30-1060U furnishes the user with real time, accurate and repeatable air/fuel ratios. The system consists of an internal air fuel ratio (AFR) controller, wiring harness, wide band oxygen sensor and a sensor bung.

PDF Books 500 Abarth technical specification

True the saying coined for Abarth-vehicles in the 1960s ("small but Wicked'), the 500 Abarth promises a compact car with exceptional performance be. It is powered by a 1.4 16v Turbo petrol engine delivers maximum 135 HP at 5000 rpm and a maximum torque of 206 NM at 3000 rpm in 'Sport' mode (in "Normal" mode is the maximum torque 180 nm at 2500 RPM). This brilliant, smooth new engine is also environmentally friendly: like the regular Fiat model is derived, the new Abarth respects the future Euro 5 legislation.Another interesting new feature of the 500 Abarth is the TTC (torque transfer control) system that improves the transmission of the drive torque to the wheels, but above all ensures that the car behaves impeccably itself in curves, so it is safer and more entertaining, drive, when you put your foot.


In accordance with the tradition of Abarth fully the styling of the 500 Abarth is no mere exercise in aesthetics, but is driven by the need to improve the performance of the car. The best proof of this stylistic approach, see the aerodynamics and functionality of certain elements.Optimized aerodynamic behavior with multiple elements, including large winged spoiler and a diffuser, which builds on the underbody, optimize the air flow output 500 Abarth, and where much of the rear bumper. We should underline, the latter help two elements - the spoiler and diffuser - pull decrease and to increase downforce at high speeds.Also the vents on the front bumper to increase sporting styling but also a critical function, cold air, which positioned feeding perform two intercoolers on the sides. That's not all. On both sides of the "diffuser", there is an exhaust pipe, cross imitating the balanced outputs of a single muffler (such as those in the 1960s). And on the side of side skirts surround the curves of the car that improves more vertical profile put on the CD.


But it is the front, that really announces the true performance of the 500 Abarth: the triple air intake consists of a central Bay, greater than the base model with a much wider top opening (of the plate) and the two ' nostrils ', symmetrical on the sides of the bumper are positioned exactly the position of the match two identical charge air cooler is only visible through the 'nose', and to ensure air circulation.

Car performance Guide Abarth

For such a small car, there a lot of attention and excitement to the 500 Abarth as is, why all the fuss for 500 with a red stripe and some Flash, looks essentially like a Fiat alloy wheels? Well, first of all it is more than that: it's super sports car like performance mad small body wrapped in a super mini. One of the unique is Fiat's new 500-looking super-minis on the road already since the Italian manufacturer's model number revived in 2007. With its quirky, sweet, fun winning styling a League devoted followers. As if you stayed the popularity to use with the younger market, enables Fiat unleashing will be the new 500 Abarth in a hungry market in 2009.

There are only 1,500 of the Abarth have tear 500s on likely available in the UK and they no earlier than their wheels dealer stock vehicles, touched so why all the fuss? As what car get an overpriced study permit essentially standing ovations at the Goodwood Festival of speed in the running along with Astons and Maseratis? Now, it is far more students than a car is overpriced. From the outside the Abarth 500 sure looks, almost identical the standard Fiat 500, although one with an odd yet strangely appealing paint job. The real difference is the Abarth Scorpion painted it almost as a warning under the hood. The standard, the Fiat 500, 69bhp, Abarth 135bhp and it offers one as well strengthening chassis straps, so that the trip exciting and rather is controlled as a terrible agony in a tin can.

Guide SCX ® presents seat 131 Abarth

SCX ® brings you a great classic from seat, one that will be instantly recognizable to an entire generation: the SEAT 131 Abarth. The distinctive colour navy blue and yellow and the diversity of the air intakes are the main features of this car certainly.The first air has a few flashy lights on both sides of the vehicle front spoiler. The grille is directly in between two pairs of headlights, and there is one more very well known air intake on the bonnet, the RAC comb, the SEAT logo and the Costa Brava rally, the sponsor of the race are printed.

In the side view of the SEAT 131 Abarth includes aprons, which are rather broad in this racing version. Can be seen in this view, including seat, demise, Michelin, FERODO, and CS) different brand names and logos.This two-door SCX ® model portrays the car Zanini Petisco, why their names appear on the door, and together with the nationality and the starting number (number one and the Spanish flag in this case). There is a more prominent air inlet on the side, behind the door. The silver cross-shaped wheels are also conspicuous in this view.
