So many great replies here, thank you to all. I will
try to answer
everything in one place.
First of all, the terminal has never fully worked
since I have had it.
Initially I couldn't even get a sensible display using the external video
connector, but I have since repaired the Basic Video board and now it
works on the external video connector. As requested, I have taken
additional pictures of the board.
Pictures here:

So many of these questions would be answered if there
was another one of
these boards to compare against. Someone must have the same board
somewhere
Hi to all!
Perhaps i have what you are looking for.
It is a VT100 from 1980 with a video board that seems to be the same as
yours. The transistor CR400 is a SANYO B411T? and this is a 2SB411
germanium PNP transistor mounted directly to the pcb without heatsink.
Where to share photos of the board with you?
