A B&K 1077 is NOT for alignment, but is good for troubleshooting dead IF stages (among MANY other uses). To Do an alignment you need a properly calibrated sweep/marker generator that works with the IF frequency of your set (different sets used different frequencies), probes, and an oscilloscope.
If you can get good audio and good video but not at the same fine tuning point you may want to try 'walking' the sound IF over to line up with the video. To to that have it fine tuned to best video or (if there is no sound at that setting) between best video and sound, then adjust sound IF for best sound, and if not at best picture setting of fine tuning, fine tune closer and readjust sound IF.
