Hi All

While performing a mod on my uBitx v4 I have heat damaged 2 surface mount diodes D15 and D15.
I want to replace them but cannot find the component values.
On the Schematic it does not state the values, only D15 and D16.
Where can I find the values to replace them ???
Thanx

1N4148 should be fine!
