[Elecraft] PR6-10/KXV3A FAILURE

[STEPHEN R]

Good morning group.  I have a PR6-10 preamp which works fine on my main radio but doesn't work on radio number 2.  I am able to receive OK through the preamp using secondary antenna but the preamp does not work to amplify signals on 6 and 10 meters.  I know the preamp works fine.  Has anyone had a failure of their KXV3A interface causing similar problem?  Thanks and 73, Steve W0SZ
