Crystal Set Circuits
THIS IS THE VERY FIRST “CRYSTAL SET HANDBOOK “
PUBLISHED IN THE TWENTIETH CENTURY!
(Printed
on 100% acid free paper stock by Paul Nelson)
It is hard to say how many thousands
of this Handbook we've sold to satisfied Hams, and many engineers, and other
professional men and women who build these sets in their spare time.
All circuits are practical
and have been tested over a long period of time. We do not copy plans as so
many of them don't work right. Most of these plans are original with us.
Hundreds of good DX reports have been received by us from fans.
The schematic, pictorial
and layout diagrams are clearly made. You don't have to be an expert to build
any of them. They run from simple sets to one of 5 controls. Diagram parts are
all numbered for simplicity.
Every inch of space is
filled with useful information.
We have added many sketches
of panel layouts, variations, and details not found in our original plans. Also,
any semblance of tube rigs have been replaced by purely crystal sets.
Circuits are shown that
will stimulate the beginner or ones that will give the old-timer a good run for
his money. Parts lists are shown, all of which are easily obtained. A good part
of them may be home-constructed.
