Tube cross-reference
M8083 alternatives, equivalents, and replacements
Review exact electrical variations and directional substitutions recorded for the M8083 voltage pentode. Compare core specifications and verify every restriction before using a replacement.
Exact variations of M8083
These designations belong to the same electrical variation group. Their names may differ because of international standards, manufacturing tolerances, or materials, but they are recorded as electrically equivalent—not merely substitutes.
Where M8083 can be used as the replacement
In these recorded relationships, M8083 is the replacement tube. The listed original tubes are not automatically suitable as replacements for M8083.

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.
