Electronics Illustrated, 1971, May, has two Dolby articles. One about the man and his life. The other about Dolby A and B processors which had just become available.

The schematic of a Dolby B circuit has one error for sure (1000uFd 1% has to be 1000uuFd 1%), and maybe others.
BTW: Art Margolis was a very regular byline in EI and in bookstores, but Sylvia Margolis (I assume wife or other family) only seems to have two credits.
