THEORETICAL CIRCUIT DIAGRAM. C1, C2, 0,0005 mfd.; C3, 0.0001 mfd,; C4, 0.0002 mfd,; C5, 0.0005 mfd.; C6, 0.0003 mfd.; C7, 0.0001 mfd.; CS, 0,003 mfd. or larger; C9, 2mfds.; C10, C11, 0.002 mfd.; R1, 2 megs.; R2, 2 megs.; R3, 600 ohms. The 600 ohm resistance R3 should be readily procurable, as resistances of about this value are in common use as series grid resistances, A suitable resistance can, however, be made by winding a few yards of very fine Eureka or other resistance wire round a small flat piece of insulating material.
