[Elecraft] K3 that has gone deaf - Solved / Fixed

[George Fremin III]

To close this thread - it appears I fixed this K3. 

After some hints from folks here and looking at the schematic 
and N6TV showing me where I could find a part number. 

It was D25 - this is a PIN diode on the bottom of the main board.
I ordered a few from Mouser, in case I destroyed one or more installing them.
They are small and inexpensive. 

I replaced it last night and the receiver is working. 

Thanks for the troubleshooting tips.
