I9BG6GA
6BG6-GA, Outline 25A, OUTLINES SECTION. Type 6BG6-G maximum dimen-sions: over-all length, 5-11/16 inches; seated height, 5-1/8 inches; diameter, 2-1/16 inches. Tubes require octal socket. They may be supplied with pins 4 and 6 or with pins I, 4, and 6 omitted. Vertical tube mounting is preferred but horizontal opera-tion is permissible if pins No.2 and 7 are in vertical plane. Type 6BG6-G is used principally for renewal purposes.

• The duration of the voltage pulse must not exceed 15 per cent of one horizontal scanning cycle. In a 525-line, SO-frame system, 15 per cent of one horizontal scanning cycle is 10 microseconds .
• Under no circumstances should this absolute value be exceeded.
tt An adequate bias resistor or other means is required to protect the tube in the absence of excitation.
_ The dc component must not exceed 100 volts.
