Tube cross-reference
6AE8 alternatives, equivalents, and replacements
Review exact electrical variations and directional substitutions recorded for the 6AE8 voltage - triode (with diode, heptode or hexode). Compare core specifications and verify every restriction before using a replacement.
Where 6AE8 can be used as the replacement
In these recorded relationships, 6AE8 is the replacement tube. The listed original tubes are not automatically suitable as replacements for 6AE8.

Verify before substituting
Matching a base or heater voltage is not enough to prove that two tubes are interchangeable. Check pin connections, heater current, maximum ratings, bias requirements, warm-up behavior, and the equipment manufacturer’s service documentation before making a substitution.
