If it keeps burning out check the wiring section of the board that is powering the transistor.
A contact or a bad diode for example can cause the transistor to blow recurrently.

    Check with the multimeter if there are more faulty components on same area of pcb. check wirings to the unit, if it is a Amp final transistor a short on output wiring can burn it.
    Check if oxyde on the board or connector may cause a short, also inspect cold joints on board.

Determine if an analog receiver has blown a channel

When you need to replace the output transistors, do them both at the same time with a matched pair. That way you won't unbalance the power supply and will be assured of the same power out is available on both channels.

Behringer EP2500 drawing large current when powered up

If you are pulling the transistor that drives the final and the problem goes away, is the driver bad? Is the power supply a multi channel isolated unit? Could the channel for that side be bad?

Sansui sdtv is having a color issue ~ green is gone and picture color is more pink or red than before

To or three likely possibilities, there is an open element in the green gun of the picture tube, or the emission is very low, the other possibility is a shorted video driver transistor on the video board.

Blows fuse when turned on

this is a normal behavior if one of the power supply transistors have blown. take the unit to an enlectronics repair. they can either change the transistors affected (usually more than one) or replace the power supply board.

Marantz SR19 no sound?

When replacing output transistors on amplifiers it is generally a good practice to replace the output capacitors as well as the biasing resistors. Just because one transistor is bad does not mean that that is the whole problem. Look for what caused the problem. Bad speakers,bad wires,defective traces on circuit board,poor soldering. Also when mounting the transistor make sure it is insulated and grease it with a dab of silicone heat sink compound. Whenever I service a board I examine all components for tolerance as well. A resistor marked at 1% tolerance,example 1k ohm + or - 1% should read no less than 990 ohms and no more than 1010 ohms. Anything else your asking for trouble. Another point is that some amplifiers use matching pairs. Pairs complement each other in an output stage and must be replaced in pairs. I repaired a Sansui Amplifier a while back and it looked as if a power output resistor was burned. Comparing the two channels I figured the matching value from the other side and replaced all of them and the system has worked flawlessly for years now. I am a retired electrical engineer and have worked in a few areas of electronics for over 35 years. Hope this information helps you.

My sansui g-7500 is burnig the transistors of power

Well that means it is done. There is no magic button to stop this I am afraid. You could replace the board but cost wise just easier to buy a new one.

Amp : sansui au11000 blown transistors on driver board

may i ask you did you put silicone grease in your transistor and apply a good mica insulator in all of your transistor---------look for any burnt resistor or explosive capacitor -----check for scew tie your supply voltage to earth by wrong.
