A passing glance at the picture
diagram would give you the impres-
sion that the circuit is very dimcult
to construct and Operate. *In reality
the reverse is true. ' k
The wiring is fairly simple as the
tion or the filament'leads which are
shown at the rear of the picture?
diagram. Most of the connection!»
consistrot short wires, from the sock-e,
éts to the transformers. j,
It you have had little experignoé;
kind I would not advise you to "at?
tempt this one as your first. While
no trouble should be experiences;
due to the fact that every piece of
paratus is plainly marked and shown
in position, it trouble should devel-
ope‘ it may be rather dlflicult for you
to find the cause and remedy‘lt.
The cost of the Various parts to
construct this recelver is over one
hundred dollars and my only reopen
for presenting such a. complicated
receiver is to give the-[lyed-ln-thef
wool experimenter 9. chance to go
