[Elecraft] K2 KDSP2 - C1 value, surface mount

[Don Wilhelm]

Dave,

The KDSP2 schematics are in the KDSP2 instruction manual.

The schematic shows C1 on the DSPx module as a 10 uF/16v capacitor 
(probably tantalum, do not reverse it!).  If the capacitor itself is not 
damaged, you can likely make a repair with small gauge wire, assuming 
there is enough intact solder pad attached to the board to keep the 
capacitor in place.
