What reading level is Radio Broadcast volume 7 book?
To quickly assess the difficulty of the text, read a short excerpt:
It is our purpose here simply to make some observations which may aid the experimenter in his constructional work.
In a detector circuit it is desirable to have the re- turn side of the secondary coil connect to the positive filament lead so that a positive voltage be applied to the grid of the tube. This is quite necessary for rectification purposes.
Now in an amplifier circuit, it is desired to have the return side of the secondary of the audio trans- former connect to the negative side of th...e filament lead so that the amplifying action will take place, figuratively speaking, on the straight portion on the vacuum tube characteristic curve.
By placing a rheostat in the negative line, a varying negative potential of from o to 6 volts may be obtained, providing the return side of the audio transformer secondary connects to a point on the rheostat winding. The value of this negative po- tential will depend upon the location of this connec- tion on the rheostat winding.
Naturally if a C battery is used there is no need for obtaining a negative grid bias in this manner.
