These collections of vintage pro audio manuals, schematics and articles are
the result of spending a lot of time and resources while learning the technical
side of the recording process. It's frustrating when one wants to learn about how
a device actually works and the only manual available is a horribly made and
grossly overpriced photocopy. These DVDs are available for the pro audio enthusiast who has an inquiring mind. About 95% of all the files on the disks
were scanned from original documents. The files were not simply swiped from
the web. These .pdfs were made from very hi-res scans. The resulting pages
were then cleaned and straightened and non-original markings were removed
were practical. All schematics have readable details. Click on a disk to view it's contents. Note: Many of these documents are reproductions of manuals and
catalogs of equipment long out of production from companies no longer in
business. Other documents have been placed in Public Domain, and there
are self authored documents included in these DVD's as well. I respect copy
rights. Please E-mail me with concerns regarding copy right claim. I certainly
don't want to offend or profit from ill will.
ps. these really aren't very profitable, more of a labor of love


Note as of 6/1/15:
I'm starting to phase out the sales of DVD's. The entire
ProAudio Schematic, Manual, Catalog collection and
Coil Winding Volumes 1 & 2 are now available for
FREE download !!
The DVD's are only shown as reference.
Many of these files are very large and downloading all of them
will take days so I'll still offer the whole collection on one USB
at a reduced price (now available on E-bay).

I will also phase out the Coil Winding DVD's except Volume 3
which contains all of my Audio Transformer dissections.
Volume 3 is still available on E-bay and the 4 DVD Coil Winding
collection, including Volume 3, is also available on E-bay
on one USB, again at a reduced cost . My E-bay auctions
link is at the bottom of the page.
