RE: Choke power supplys in Comp Symmetry BJT power amps

Posted by Charles Hansen on August 19, 2011 at 17:07:01:
DJK is right. Ayre used choke-input power supplies in our original five products, of which two were power amps. The cost of the power supply (which is a significant fraction of the entire product is doubled. Plus high-powered chokes create a high-powered mechanical buzz that customers hate.

There are other ways to skin that cat that don't have the drawbacks of chokes. Please also note that there is a BIG difference between a true choke-input power supply and a power supply with a choke. The latter is more of a gimmick, created largely to give the marketing department something to spin.
