    Default Search urgently 2 transistors


    Hi looking for, 2 more than one, depending on the price diodes in the TO-220 housing Namely the power supply in an system installed and F2 500 mk2 over 60-70%. Does anyone have this Fast Diodes or 500 F2 or does anyone know an online store where you can find the. I have Not even found in the RS Hope someone knows what has or what, would like to repair the amp.

    Has not just some little info that might make me more? Equivalent Also a diode would be enough for me.

    Hello, this amplifier power supply was technically particularly badly abused therefore it could be that it has cleaned the. Since so electronic parts do not cost the world to me if it were not matter if I am only 60% sure that they are broken. I admit that the measuring method is anything but professionally but just simply and quickly and finders could also quiet possible. So: The board has indeed 2 transformers and a 2 of these diodes with 4 other transistors. The only problem is it is not just the power is because they get enough. If you still want to know, just ask.

    In the electrolytic capacitors I measure 47v-0-47v or 94v at about 14V input voltage. Unfortunately, I have no idea how such a power supply in special funkiness and do something or make it or may not want. As I said the amp works, too just not all the power she community. Also strange is that you do to create the momentum more than continuous load, because if I eg adjusting a frequency on the PC and the running leave and then with the volume slowly, then it also creates a lot more like 30A only normal to hear music with bass beats she goes to protect.

    May be schoolmate thought that the tension may simply collapse and they only reason you switch off? Or simply due to overload makes? can indeed be deliberate.

    That can not be, because then everything would burn on the secondary side by the AC voltage from the power supply. I looked at the board of funny. What's that about the right power connector where the brass bridges long run? Solder? And why is missing one of the safety implications? That looks kinda like charred. You wrote earlier also would work the originals no longer reclosure and you turn on different? What do you mean exactly?

    Yes that is solder as he had draughtboards only the remote. fuses are OK, that is just a charred alligator clip with the I give the remote voltage. But 60A + crocodile clip bridge is safe enough because it always turns off at 30A. Right behind the Elko is also a black wire soldered this is for new activation because it had blown this transistor. I know unfortunately it is verbalization total but except for the one problem they would yes go.
