Mission Loudspeaker Repairs
Mission 770 Loudspeakers
These were wonderful speakers from 79-81, the sound was crystal clear. I know I've just repaired a couple, but time will take its toll on most things. The wire used in them is more like welding cable and as such tends to pull the speaker terminals off the speaker chassis. So if they begin to sound distorted or intermittent then this could be the problem. If your lucky they can be glued back into position (the bass driver). I used short lengths of flexible wire to join it to the speaker, the drivers are made by Seas with a die-cast chassis on the bass which tends to corrode and turn white, late serial no ones used lower quality drivers even though all the advertising reckoned the change was an improvement!
