[Boatanchors] Oscilloscope

[Joe Walden]

Hello again,From Joe w5jdy in Okla...  Well,as always,I am seeking info.
This time for an old oscilloscope Military Model OS-8/U.     I am sure some
of you have seen or even worked on one of these scopes before.  I sent off
and received a Manual but it is for a OS-8C/U.   the 8/U has 8 tubes and the
8C/U has 10.   They are all together different.   Lets see if anyone knows a
problem,or two, these models have in common..   The problems I have in the
8/U appears to be in the Power Supply as the scope tube will Not focus
properly and the wave form has a hicky in it.  All the other controls work
OK and the Vertical input and sensitivity is also OK.   Yes I know these
scopes have no value and are of little use...  just fooling
around.re-inventing the wheel,in Norman Okla.  Maybe I can use it for a
curve tracer?   Joe w5jdy

Can someone point me to a site to get the Right Schematic????
