These Schematics are copies of material I have collected over years of servicing Recording Studios and Film Studios.   Some of these have been floating around on the Web, and where I managed to log which site they came from, I have given credit to the Original Poster...and these are completely free to use for yourself in a 'non-commerical' way.

  Those for "Sale' are things that you are paying me to make the Zerox copies for you or to scan for downloading, and you're helping to keep this site up and running.     Basically you are just paying for my time and costs involved.  ! !     In many cases I have gone out and 'borrowed' someone's manual, gone to the Zerox facility, spent an hour Zeroxing a copy, then drive to return the Manual to the Owner, then spent another couple of hours 'scanning' the manual and editing the material, then putting it up on this site.   Al that takes hours and hours to do for each manual.  It's not 'fun', it's work.   But a lot of these Manuals and Schematics are unavailable elsewhere, and I want to help keeping Analog Gear up and running.
