The picture shows different variants for German telegraph
relays. Trls43a was found in NTG2, but I haven't the
faintest
idea where Trls44a was used, found it at work amongst a lot of
old components, so it may have been used for some sort of
telecommunication
My 2nd XY-scope using Philips DH3-91
miniature oscilloscope tube, built around 1990, and used for 20m
RTTY and packet radio
tuning (300Baud), The first had 2AP1, which were relatively
inexpensive around 1980, but you had to make your own socket.
