@IRON HORSE posted:I bought a Hunter 300 watt landscape transformer several years ago that gives off an annoying whine. I never returned it and probably should have. A few years later I bought a 600 watt version that makes zero noise and it a work horse. I bought both of them for powering lights and some accessories.
Why does one whine and the other does not from the same manufacturer? Should I assume one is just defective?

It's not defective if it supplies power and does so safely. The whine is an undocumented feature that allows the price to be reasonable.
If you don't like this feature buy a more expensive unit.
The marketing whiz that signed off on the whine was betting that the end user would prefer a less expensive unit over a quiet one. As such this is a marketing issue and not a technical one. So, from a technical perspective it's not defective.
You get what you pay for.
