SOURCE: Power adapter of Avocent SwitchView® 1000

Usually, you can get away with a 12 DC adapter, at about 1 - 2 Amps, preferably switchmode. The center Pin is Positive & the Outer is negative. Most computer "Things" require 5 Volts & under for the IC's etc, and 12 Volts for Other communication IC's and Motors etc. So generally 12 Volts is a good choice. And you could get a 10 Amp unit because it will not matter as a unit will only "Draw" it's maximum, of whatever that is. So if the max draw was say 1 Amp, well a 2 Amp would be fine, but if the reverse were true it could not work. You also need a little head room, too which is why use use a 1:1.5 ratio, IE: The unit draws 5 Amps, your supply should be able to provide, at least 8. Now if you check on your unit it may even tell you the wattage, if this is the case, divide that figure by 12, that will give you the Current required in Amps, just get a supply with slightly more.

SOURCE: trying to install subs

If there is no red and black colored input wire connectors on the subs then it doesn't matter.Positive and negative does not really effect speakers and subs since it is DC anyways.

Are you sure you getting enough power to push everything. I have seen when the voltage is too low coming in, the amps will shut down so they don't overheat. Once they've cooled off and the volume level is lowered they will kick in again. Low voltage and a heavy draw will create massive amounts of heat.

Check all the other component on board, associated with this MOSFET cirlcuit. Especially shorted zener diode, capacitor/s etc: Never replace an other FET, without check all the related component. It too will fail. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

There is no danger from electromagnetic waves. There is certainly less than a 1970s Television. The manual didn't tell you very much unless you want to repair it. If you know about big amps, you know all you need. you won't be running bridge mode. The input can be shakey since its not really balanced line. Sometimes pin 2 is "signal" sometimes its pin 3.

Amp over heating and cutting off


sounds like the Impedance of the speakers does not match that of the amp, therefore the output stage of the amp is trying to compensate, driving the amps too hard and eventually causing the thermal cut out to activate. Check the ratings on everything are compatible before you start sending it off to be fixed.

I need to know what kind of fuse my amp takes...


IT MAY MEAN THAT IT TAKES (2) 25 AMP FUSES
IF YOU HAVE THEM OUT SEE IF IT SAYS WHAT THEY ARE OR OPEN IT UP IT MAY SAY IT ON THE BOARD OR THE FUSE HOLDER OR LOOK @ THE SPECS ON THE AMP SEE WHAT THE TOTAL CURRENT IS YOU CAN ALWAYS START WITH A SMALLER AMPAGE LIKE 10 -20 AMP FUSE ALWAYS GO SMALLER

T1500-1bd burnt mosfet


First of all is the mosfet your talking about in the output section or in the power supply section? Most car amps use mosfets in the power supply section, some use them in the output section. To test the transistors in your amp, take a digital volt meter and set it to diode check. Then take the leads and put them accross the first and third legs of the transistors. Usally the red test lead on the first leg and black test lead on the third leg of transistor. If you get a reading of 000 then transistor is shorted. If you get a reading below 600 then transistor is on it's way out if not allready or it's next to a shorted transistor that is it's complimentry output transistor. comonly you will have 2 transistors working together, one NPN and one PNP per a channel, or 4 of them in a bridged type output circuit depending on the watts and how man channels your amp has. I was just looking at the specs of this amp and it's got me confused. It says it's a 2 channel but looking at all the info on different pages it says at 4ohm:200wattsx4 and at 2ohms:300wattsx4 and 1 channel mono 600watts into 4ohms. weird for a 2 channel. anyway that is how you test your transistors. Same way for the power supply section but, you will come accross a couple or more switching diodes that look like transistors and you will get a 000 reading when you test those like I specified. They rarely go out and most of the time there is only 2 of them. They will have a diagram like a diode on the front showing you which way the power flows. Let me know what you find out. Your amp should have went to protect mode if you smoked a mosfet.
