These are permanent archives of old sections of diyAudio that ran on old legacy platforms, and were unable to be migrated to new platforms. In the interests of the stability of the forum, these unsupported platforms have been removed, and a read only html archive of all the content has been preserved circa July 2017.

Some of the archives presently show ads, even if the browser is a paid diyAudio member who has elected to turn ads off. This will be remedied shortly.
