If its not something silly like a slipping belt, then,
usually its a small electrical part failure.
Go to a E-type website and see if there is a common way that these alternators fail.
Check and see the availability of these parts---rectifiers, brushes, diodes, internal regulators, etc.
Fix it yourself, or take it to an autoelectric shop.
Also a possibility exists that the alternator can be rebuilt--looking stock externally-- but have completely revised internals, with higher amp output.

There are specialized shops in rebuilding alternators.

diode trio or internal regulator are usually what goes out on Lucas alternators.

Check diode bridge

If by slightly off you mean the voltage is like 12.8 instead of 13 to 14 then one of the diodes may have failed
