Wiring & diagram Info

This is a very simple, low cost, Hi-Fi quality power amplifier. You can build it 5 ways, like it?s shown in the table (from 20 W to 80 W RMS).

Some comments:
- The first thing that you must do, is to measure the end transistors (T3 and T4) amplifying coefficient, the hfe or ?. If their disagreement is bigger than 30 %, the amplifier would not give a clear sound. I used MJ3001 and MJ2501 transistors, and this disagreement was around 5%.
- Before the first ?turning on? you must short circuit the inputs of the amp, and put a mA-meter on the output, than turn the amplifier on, and tune the R13 pot, to decrease the DC current on the output, to some uA-s, or in a lucky situation to zero. I was able to decrease it to 10 uA.

Motorola is currently preparing to produce a new variant of the Motorola DROID X and is rumored that the phone will have the name Motorola Droid X2, this phone is also known as the Daytona.


We currently have leaked information about the official specs of these phones that we can from the site PocketNow, and here are the features available on these phones:

* 1GHz dual-core 2 processor Tegra
* 4.3-inch QHD capacitive touchscreen (thats 540,960 pixels)
* EV-DO Rev. A connectivity
* 8-megapixel camera with dual-LED flash
* Wi-Fi 802.11 a / ​​b / g / n
* HDMI out
* Bluetooth 2.1 + EDR
* Proximity, ambient light, accelerometer and compass sensors
* 8GB of internal storage

The plan of this phone will be bundled by the U.S. Verizon Wireless network.
