. . to use too much; just enough to give a not-too-thick coating on the plate.

Interesting, I too at times hear the same high pitch at the mid (auto) to high settings. I've replaced mine a few years ago and mostly run it on one to two clicks above MIN, so no whine but it's there on higher settings.

Sounds, like it's a by-product of the new regulator. Tnx for letting us know.
