I have a couple of small scopes, for example the
Cossor 1039 here:

which has three valves as well as the CRT, and was intended for TV service.
Somewhere I have the issue of Practical Television magazine which gives
construction details for a 1 valve + CRT scope. OK, there are some
semiconductor rectifiiers in the PSU too. The valve is for the timebase,
the Y input goes straight to the CRT plates. But it was useable for the
signals in vavle TVs of the time, and a lot better than nothing.
really like is a 549, if anyone with in a 100 miles of
London has one they
no longer want :-)
Woudln't we all :-)
