I will train you quickly and inexpensively during your spare time. There are very few unusual features about this tube, but there are several points which should be given detailed consideration. The grid-return circuits of the two I. Durham carbon resistor, ohms, R4 ; Two I. As before, the R. Chapter I—Fundamentals of Radio: Of course you want to make sure that any particular church would benefit by the addition of a P.

Low cost of construction. Often, during a given period, there may not be any classical music, and if you have no printed program before you, which often happens, you are at a loss to know whether there will be any such music on the air that evening or not. The chassis was removed from the cabinet 157/4 a black, with yellow-tip resistor was found to be burned. Returning to the shop, I touched the coils with the litmus paper; it turned pink, indicating an acid condition which was causing the coils to absorb moisture, no matter how kc times they were dried out.
This filter is a one section pi type.
This contest closes on the 15th of every month, by which time all the Kinks must be received for the next month. The miniature copper-oxide rectifier is a Tau-rex; the meter, a Weston O-l. There arc hundreds of opportunities 157/4gg you to have a spare time or full time Radio business of your own — to be your own aduiola. The two-stage audio amplifier is of standard design. Oscillations arising from such causes are due to interstage coupling. It will be noticed from the diagram that some manufacturing economies 15/74g R.
To make adustments of the I. Series, To me a completed receiver is only as good as its speaker or phones. If further “dope” is received, we will publish a similar list in the near future.
The combination first-detector and oscillator, V2, in addition to performing these functions also has a gain figure of 40 to 1. V7 to V10, 26 ma. Durham carbon resistors, 1. List of Parts One Acratest input terminal strip No. The mutual conductance of the tube is first measured in the usual manner; then the applied A. At least seven or eight separate measurements are made for each audioa.
The first cause of oscillation may be cured only by electrical means, but the second cause may only be eliminated by mechanical methods, since the source of the trouble is due to the kinetic energy energy due to motion of the sound wave auiola from the speaker and entering the microphone. B is the new W.

Models, and kc. The use of a P. The complete design is indicated in Fig. More than one repair man has vainly tried to line up supers at kc. We either have he tube you require id we will make it for you.
The recommended antenna length is 40 to 80 ft.

Models 89, 90, 99, 99A, Completely wired and tasted. The miniature, copper-oxide rectifier and meter are connected in series with the input resistors terminals 9 and 11 to terminals 1 and 2 to adjust for line-voltage variations; and, to read mutual conductance, are connected with the blocking condenser, across either R5 or R6, depending on the type of tube under test. The set was then brought to our shop for examination. Housed in moisture proof paper tubes. The distortion characteristics of this type tube are given in Fig.
