II would b., impossible in an article
of this kind to give the operating cnar-
acteristics of all the tubes on the mar
l,et Most of the independent tubes
,re patterned after the original Radio
CORPORATION and Cunningham tubes,
so that a general idea of the charac-
teristics of the Independent tubes can
he gained by finding out the Radio
CORPORATION or Cunningham tubes TO
which they are equivalent.
The tubes marketed by the Radio
CORPORATION and the Cunningham Co.
are both identical, but are sold under
different type numbers by the Two
concerns.
"Soft" Detector Tubes.
The first in the list are the so-called
soft" detector tubes. The wv zoo or
the Radio Corporation and the Z 800
of the Cunningham Co. are 1dentlcai
both mechanically and electrically.
Both have the standard Navy type
base. The UN 200 and OK 300 are the
same as the wv 200 and G 300 cleo

large type standardized UN or OK
base described earlier in this series.

Use as Detector.
1t operates best as a detector under
fine control of filament and plate volt
age, so that vernier rheostat and po-
tentiometer control of plate voltage is
desirable. 1t is not suited for use as
a radio or audio frequency amplifier
and should be used only as a detector.
1t is rather hard on filament bat

The wv 201 and it's counterpart,
C 301, have been superseded by the
improved types of ampIifier tubes.
These have not been produced with
the new UX and OK bases, because Of
the small demand for them. Their
electrical characteristics as far as fla
ment voltage and current are the same
as those of the wv 200 and c 800.

Perjury and Swindling Charges

Hoffman, general manager of the Hoh-

yesterday by the Travis County grand
jury on charge of perjury and swim

way surfacing contract.
The indictment was returned in the
midst of court proceedings in which
the State of Texas seeks to recover
from the Hoffman concern nearly
$500 900 in alleged excessive charges
on State highway contracts. 1t wa the
first criminal charge brought as the
result of grand jury investiga tions OF
the conduct of State highway affairs
under Gov. Miriam 4. t'ergusons al.

The grand jury, reporting after
weeks of work. declared that the let

way Commission. They resigned at the
request of Gov. Ferguson after At

In order to meet more nearly the
demands of readers for a certain few
expensive books of non-fiction, the
Public Library announces that in the
future, in addition to the regular
copies of such books which are circu-
lated free of charge, they will pur-
chase duplicate copies of such books to
be loaned on the payment of small
fees. These fees will go toward pay
ing for the books, and when this is ac-
complished The books will be made
free copies. The library has used this
method for many years to meet the
demands for popular fiction. 1t will
enable readers to secure the best books
of non-fiction at the height of their
popularity.
Books costing under $3.50 will be
lent for 10 cents an issue of one week
for each volume, and those above that
price for % cents per volume an is

reader may borrow either one or
both vlumes at a time. In cases where
there are rental copies of books of non
fiction the free copy may not be re-
served, it is announced.
