Per their homepage, "Since
1946 SAMS Technical Publishing manuals have been the standard that repair technicians
have insisted upon having to provide professional repairs to their customers. Our
original Quickfact manuals and Photofact® manuals have been designed to provide
reliable, consistent repair data for electronics repair technicians, antique electronics
restorers, and hobbyist. SAMS Technical Publishing has been the gold standard in
the repair industry for TVs, VCRs, Radios, etc. Why would you settle for anything
less than the original? For those models and/or chassis not covered by SAMS Photofact®
manuals or Quickfact manuals, we have available OEM owners manuals and service manuals
that can be ordered in both hard copy and electronic formats." I bought schematics
for my 1941
Crosley 03CB console radio from them. BTW, if you happen to know anything about
the "PEET" program mentioned at the bottom of the page, please let me know. I cannot
find information about it anywhere.
Howard W. Sams Photofact Ad
 exclusive in Photofact the world's finest
electronic service data
the famous Howard W. Sams Standard Notation Schematic!
as easy to read as a road map ... makes circuit tracing and parts identification
simple, quick, accurate ... saves you hours each day for more profitable servicing
...
This Amazing Feature-Packed Schematic Gives You All the Right Answers at a Glance!
1 Uniform schematic layout. Each receiver circuit can be located quickly, since
layout is always the same, regardless of receiver make.
2 Voltages are shown at all tube pins and test points for speed and convenience
- no time-wasting separate reference charts to fumble through.
3 Shows actual photos of waveforms at key check points for quick comparison with
those obtained on your own scope.
4 "CircuiTrace" numbers on schematic are keyed to actual photos of printed boards,
for easy location of specific circuit points.
5 Component item numbers are keyed to chassis photos for parts location, and
to parts list to enable you to quickly determine proper replacement.
6 Special capacitor and resistor ratings are shown on the schematic; valuable
where tolerances are a factor in replacement parts consideration.
7 Coil and transformer color codes or terminal identifications are given to speed
tracing of connections.
8 Test points are shown for speedy reference in measuring and servicing.
9 Special currents (B+ supply, horizontal output cathode, vertical output cathode,
etc.) are given, to isolate improperly operating circuits or components.
10 Alignment points are identified on the schematic and photos, and are keyed
in with the alignment procedures for rapid, error-free adjustments.
11 Tube functions are shown on schematic and Tube Placement Charts to help you
quickly isolate troubles.
12 Complete identification of controls and switches quickly shows their functions
without needless circuit tracing. Arrows Indicate direction of rotation to help
you understand circuit operation.
13 Coil resistances over 1-ohm are shown - a great help in determining shorted
turns, opens, etc. - avoids misleading continuity tests.
14 Polarity and section identification of electrolytic capacitors are easily
determined from the schematic -saves valuable time in identifying component sections.
15 Fuse ratings are shown on schematics and Tube Placement Charts for quick replacement;
handy for in-home service work.
The Standard Notation Schematic is just one of dozens of great features in Photofact
for fastest, easiest, more profitable servicing. See your Sams Distributor for full
