Re: lost power supply
We couldn't find the info regarding output/voltage. However, there is an online vendor offering replacement chargers/batteries for the T5500. Here is the link, look toward the bottom of the page for the chargers. http://www.csonline.net/crawford/motorola_talkabout_T5500.htm

Should it be a power supply that outputs AC and converts to DC inside the speaker case, or is it a wall adapter the outputs DC straight to the built in amplifier? Some speakers have the voltage and polarity for the plug on the back of the speaker where the power lead plugs in. As they are only small speakers of probably a couple of watts it may only need about 2 Amps or less. Higher current is fine as the amp will only use what it needs to work correctly but I would'nt go below 2 Amps.
What??? There is NO output transformer for the Mg50DFX. The outputs are direct driven from hybrid stick TDA type solid state amp chips.
The power transformet is probably about 100 watt size and supplies two voltages... one that feeds a +/- 15 volt three terminal regulators... Probably 22 volts +/- to the regualtors and the other supply will be unregulated to the power amp chips.
Have a look at one like yours in store & see what specs are on plug in to charge. It will say Output voltage ..., then how many amps, or milli-amps, for example: ( output voltage 13.5 VDC @ 800ma.) Now find a charger/adapter, with same specs, and plug. Perhaps one your using is very minimal output, or lower voltage. Be sure polarity symbol is same on both too.
Ran across your request for information about the cables needed for hooking up the Umax Astra 1220U scanner. The scanner require a standard older version USB cable that hooks the scanner to your PC. The second cable is the Power Supply Adapter cable. The information listed on the Power Supply Adapter is listed below.
P/N 490081-03
Input 120 Volt @ 60 Hz 0.3 amps
Output DC 12 Volts @ 1 Amp
Model # RWP481212
You should be able to get the scanner to work as long as you can find any power supply that has the listed Input/Output ratings, an adapter that will plug into the scanner.
Hope this help you.

its 12V 1000Ma (1.0A) I work in radioshack... IN fact Im dealing with this problem as I speak... I need the Polarity for this however, otherwise theres a 50 50 chance this might get blown.
