Note (3): For optimum life, heater may be supplied from a source of 10.8 i 0.2
volts through a circuit resistance of L.16 ohms.

Note (A): Cathode connected to shell through cathode to shell capacitance.

Note (5): With the .750"-L0 thread acrewed into a guage having a thread with
a .750"-A0 class 1 fit,the .856", 1.070" and .180" diameters must
fit in cylinders concentric with the .750"-L0 thread and having
diameters of .895" x .720 long; 1.135" x .157" long; and .210" x
.375" long. Allowances for these tolerances must be made in any
circuit design.
