Suitability of 1LG5 electron tube as battery powered microphone preamplifier?


At your risk. Take all safety precautions. Any voltage or current can be dangerous. A fuse must be used in series with any battery for fire hazard safety.


This is the datasheet:

Advantages:
Very low heater supply power.


Remote cutoff or vari mu or vari μ (actually in Hellenic language μ is pronounced mee with short ee ie phonetics code "mi". Same as π, pronounced πι, "pi" and not pie).


Suppressor grid not connected to cathode.
