px22 amplifier component burn out
a 5 lead sot-23 component that is positioned in the center of the PCB of the px22 amplifier has burn-out due to overcharging
On both sides of the PCB this 5 lead component can be found.
The description on the component is R9G5 (not burned out), and a description that looks like R9BT for the burned out component.
I have seen other amplifiers and the description of the components differ. R91V/R91W is a combination, R905 I also found.
I would like to now what kind of component this is.
Hereby 3 pictures.
The red squares show the component of interest.
On the side of the turing wheels the component is burned out. I added a more detailed picture of that image.
Hope somebody can shed some light on what these components are and whether it makes sense to replace them
