Adjust the tracking control for maximum noise, if there is insufficient range, move the control head laterally with the adjustment cone.
Adjust the L & R inclined guides for uniform noise. Don't make the mistake of having both guides too high so you are reading the track above, the tape should be sitting on the ledge of the lower drum.
When you have it right you should be able to adjust the tracking control too and fro and see the picture emerging uniformly from the noise with no banding. If you see narrow bands that walk up and down the screen with the tracking control, you are way out.
Of course, then you'll want to look at the FM envelope on the scope and admire what a good job you did.

I have tried this, however when I adjust the tracking the noise bar doesnt disappear completely. Also, different tapes still don't play correctly. It does appear to play back its own recordings perfectly. It also appears to sometimes slip of its path between the pinch roller/capstan and audio head sometimes. Thanks for all the responses.
