Tube cross-reference
1H5G alternatives, equivalents, and replacements
Review exact electrical variations and directional substitutions recorded for the 1H5G voltage - triode (with diode, heptode or hexode). Compare core specifications and verify every restriction before using a replacement.
Replacement tubes for 1H5G
The following tubes are recorded as possible replacements for 1H5G. This direction does not establish that 1H5G can replace them.

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.
