Hello!

	I have recently received a Tektroniks scope that doesn't work.
There is no horizontal scan.  A dot will appear in the middle of the
screen, but will not trace left to right.  If a voltage is applied, the
dot will jump the correct amount, so this is why I suspect the scanning
area.  After looking around, I discovered a blown fuse, and a cracked
resistor.  Replacing both the resistor and the fuse resulted in another
set of dead components.  After more looking around, I have found another
cooked resistor, but this one is so discolored that the original value
is uncertain.  I am leary about going farther without a set of
schematics for this scope.  (This was a gift-No schematics-Doesn't work)

	Where can I find a set of schematics for this?  I don't know how
old it is but it is model # 5103N and ser # B021944.  Any advice would
be very welcome!
