Schematics/repair data--
Most schematics on vintage radios come from either the
Rider's Perpetual Troubleshooter's Manuals (earlier sets)
or the Howard Sam's Photofacts (post-war sets). These are
available in many public libraries. Otherwise, the following
suppliers offer schematics at reasonable rates (if you can
provide them with a model number): #1,2,4,5. If you don't
have a model number but can provide the tube #'s and layout,
for an extra fee they can usually find the right schematic.
See also "Literature".
Howard W. Sams began publishing repair data in 1947. Don't look for
schematics, etc. of prewar electronics in Sams.
Rider reprinted manufacturers' repair information, and you should look
for "family resemblances" between the radio you have and radios of the
same make---Rider may have published repair data for only one or two of
a large family of model numbers that are nearly identical. Also keep
in mind that many smaller radios built after the mid-thirties were
built to standard Hazeltine/RCA designs under license, and you may not
need a specific schematic for your set).
Tubes--
A complete list of tube suppliers would be an incredible headache
to compile. Just about all of the suppliers listed at the beginning
of this directory have tubes, and it is unlikely that you would
be unable to get what you need from at least one of them. The ones
that have their inventory conveniently listed in their catalog are:
#1,2,3,6,9. Prices vary.
