Letter from Walt Jung to Jack Walton on V4 article on power supply measurement and listening tests

Jack's article drew comments from the man who started much of the interest in power supply impact on audio circuits in the 80-ies, Walt Jung. On Walt's request Jack provides some additional information on the transformer and rectifier configurations, and takes some of Walts suggestions for an eventually follow-up test. Their exchange can be downloaded here.
