this little PA, no longer has power suddenly, on my DATV setup.
The stabilized voltage is present, therefore the RF amplifiers, one or both, are broken.
The code of the two RF amplifiers have been deleted (see figure) , so as not to recognize the model, but I was wondering if someone was able to do it.
On one of the two, the code has not been definitively deleted and KB or KR is visible
Now a new one has come from china for a few euros and I'm working with that, but I'd like to identify the broken component.
