Known Equivalents & Substitutes

5965A

Similar Tubes (Not Drop-In Compatible)

12AU7

Similar medium-mu dual triode on Noval base but different operating characteristics — higher mu (17 vs 16.5) and different plate resistance. Not a guaranteed drop-in.

12AV7

Similar medium-mu dual triode on Noval base (mu=16.5) but optimized for different applications — verify compatibility

Notes

12.6V heater only — cannot be wired for 6.3V parallel heater operation (no center-tap).
Designed primarily for computer switching circuits, DC amplifiers, and industrial control applications.
Controlled-characteristics tube with tighter tolerances than consumer equivalents.
GE Essential Characteristics lists Pa_max as 2.4 W per section, Va_max as 300 V.
