dynaBel 5kW amp fault - blown transistors +
I have a big amplifier who has some blown transistors in it. Output`s seems okey, but havent measured them yet, will do tomorrow.
The real problem is that i have no schematics over the amp, and it is some blown resistors witch i cannot read the colorcodes of, but maybe someone knows anyhow? Look at the attached pictures.
There is also a blown KIA494 PWM Controller there, TL494 would be a good replacement?
There are also some diodes there witch i believe to be wasted, called FMU32U, i cannot find information about the exact FMU32U, but i found some about FMU32. Im looking for a replacement for those to, would MUR3060 do the trick?
I would clean the resistors off with something, maybe acetone and see if they look better. Pretty sure the 494 are the same.
