Tube cross-reference

6DR8 alternatives, equivalents, and replacements

Review exact electrical variations and directional substitutions recorded for the 6DR8 voltage pentode or tetrode (with diode). Compare core specifications and verify every restriction before using a replacement.

Exact variations of 6DR8

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.

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.
