[Elecraft] Ooops -- think I fried the IF amp...

[David A. Belsley]

Ward:
   It's definitely worthy your attempting further diagnostics and 
attempts to fix.  The more you get into it, the further you will find 
yourself able to go.  And it's always nice to know, in the back of your 
mind, that Elecraft is there behind the scenes if necessary.  There are 
good odds you'll be able to do the job yourself, perhaps with an e-mail 
or a phone call to Gary, and it will be a nice feeling for sure.

best wishes, and the best of luck,

dave belsley, w1euy
