Do you have the factory service manual? If not, you can get it from hifiengine.com, or I can send you a copy.

I would suggest resetting the high and low oscillator adjustments to close to where they were, and then try adjusting each one a little at a time until you get the band spread out to your liking. You may never be able to get the dial to track exactly with the scale but...sometimes, "close enough" has to be good enough due to aging of components, etc.
