Alternators

The whine is increasing so time to get a new one before it finally dies. (Likely on a busy A road, in the country, on a blind corner at rush hour!!}
Which make to go for? Which manufacturer? Is Denso worth £100 over Lucas?
Suggestions and advice gratefully received. Thanks.

The wine can be a bearing getting dry, usual for it to be front. Try a dribble of oil behind the fan as temporary measure. Also replacement bearings are available. Check your alts output with volt meter.

Before you start spending money, check that the noise isn't being caused by contamination on the fan-belt. Spray a little bit of water on the belt and see if the noise goes.

Rotating electrics shop should rebuild, or exchange for a recon unit.
Last time I had one done for a Ninety it was 80 quid. That was probably 10 years ago, so it might be 100 quid now.

If I buy a full alternator ( or starter ), then I tend to use the Starter motor and Alternator company in plymouth - no affiliation, just a satisfied customer....

If I rebuild one, then parts from Mid Ulster Rotating Electrics are excellent quality, and the service and knowledge second to none IME..

Plus one on above, I have rebuilt alternators with parts from Rotating Electrics. As long as windings are good renewing bearings and control box is straight forward.
