Hi the Heriberto. Japanese unknown to me also! I have tried searching Google with different combinations of words but no result. You probably searched also.

3P41 Transmiting Tube Data Need
This is a small CRT I believe, 41 means long persistance phosphor as
used in radar (slow scan ham use). They were also used in early Heathkit spectrum display. I may have one in my junk pile. |

Come to think of it the number does look like a small CRT! But Heriberto is sure it is transmitting tube, possibly from a marine service transmitter. Could the 3P41 be a batch number not a tube type???? |
