I just ran across an ebay auction for the CD compilation of all issues of the late, great, lamented Sound Practices magazine. The auction appears to be conducted by SP publisher Joe Roberts.
For those who don't know, SP debuted in 1992 and literally defined and fuelled the triode / horn DIY revolution of that decade in its 16 issues. My complete stack of SPs is among my most cherished possessions. Now the whole shebang is available for $29. Recommended!
