Hi Adrian,
Thanks for your reply. So far, you are the only group member who has
expressed interest.
I attach photograph of the S31. You may be able to see that the input
connector has been changed (by the previous owner) to the more conventional
BNC type. Otherwise, I don't think there are any changes.
It is not obvious how the case can be removed, but it seems to be
constructed from 6 sections. I think that the rear panel must clip on
somehow and hold the sides in place which, in turn, hold the top and bottom
vented panels in place.
Hope the photo is of interest and you could certainly have the scope if you
don't mind travelling up to Yorkshire sometime. No rush, since the scope
has just been stored in the loft for the past 40 years!
Just let me know if you decide not to have it and I will also let you know
if there is any other interest.
Ken.

Hi Ken,
I would be interested if nobody nearer to you pops up - bit of a drive
from Eastern Anglia.
Does it have its case by any chance? Mine does not and I'm trying to
re-create one based on a very tiny, badly scanned image from a copy of a
1957 Wireless World, and struggling! All I can deduce at the moment is
that it may have been constructed more like the single '5-sided box'
design of the later S51 than the three piece 'clam shell' design of the
face-lifted S31 because it is missing all the fixing holes it would need
to hold the base part of that on. I would really appreciate a pic!
All the best, Adrian

Hi Adrian and group,
I have an early S31 model (also pre-facelift) which I would like to give
away to anyone who is interested. I also have the full, original manual
with it - including parts lists, voltages and schematics. The oscilloscope
basically works, producing a dispayed waveform from the CAL signal, but
there are some issues with X and Y shift range and timebase linearity. The
serial number on the chassis appears to 810 and the number on the
transformer is 68810.
This would have to be by collection only - location West Yorkshire, UK.
Let me know if you are interested.
Ken.
