There does not appear to be a line drive adjustment on this model. Just as an experiment try connecting a small value capacitor around 200pf from the junction of R86 and C100.

The line output transformers were very unreliable in this model if past history is correct but they normally break down completely. I don't think yours has that problem. John.
