41-255 questions
#6

7C6 is shown as a "preferred" substitute for 7B6, but the characteristics are slightly different, and the 7C6 uses 0.45 A of filament current vs. 0.3 A in the 7B6.

7A7 is a sub for 7B7. 7B7 uses half the filament current as the 7A7 (0.15 A vs. 0.3 A), but the characteristics are otherwise nearly identical.
