I am working on some old tube amps for jukeboxes and decided to revive 
my ancient IM-48 Audio Analyzer (I have a shrill distortion to track 
down), but the documentation I had was ghastly. So I hunted around on 
line and found bits and pieces available for download here and there and 
have now built up a manual that is actually useful.

If that is of use to anyone it is now up on the FTP site...
