i was given an XT400 that won’t key. I am running a Johnson Messenger White Face into the amp.
When all hooked up and amp off I’m getting the normal 4watts dead key and swing to 8 watts. When the amp is turned on the relay never closes. If I jump the power from the remote to the relay it will close the relay when keyed but I get 1watt out and a very bad sine on the scope.
Im not very familiar with amps so not sure we’re to start looking?
