Working on a RCI-69VHP (bought new from dealer in USA, I am located in Sweden). Same board as RCI-69 base, i.e. EPT690012D.
I see a strange mod where C112 has been replaced with a diode and a tantalum cap (as far as I can see):


Maybe the tantalum cap is original and a diode has been soldered in series?
I am wondering this is a true mod done by the dealer or is it like this from the factory?
