Source for replacement caps in H744 regulators

FWIW, none of mine are silent under load. If they're not being loaded (e.g. on a test bench, with no dummy load, or if you have all the boards out) they can whine excessively due to no minimum load. Beware cheap test equipment. $client has a few of these Chinese handheld LC/RLC meters, they're wildly inaccurate on some parameters, including ESR on large electrolytics. We've got a proper Gen-Rad RLC Digibridge in the shop to compare against. We couldn't figure out why some of their tuned filter stages were failing QC at a much higher rate than expected. They were off-frequency because the cheap meters were giving consistently incorrect measurements when trying to match capacitors. That said, it's not like replacing them with new will *hurt* -- it just might not fix the whine. Thanks, Jonathan
