Tektronix 2225 timebase problem

hello all,
I have a problem with a tektronix 2225 scope, the timebase isn't
working, all I have is a beam movement on the vertical axis, nothing
in the horizontal axis.
anyone can help me with this? or else anyone can send me the service
manual with some electronic diagrams of the timebase circuit?
many thanks in advance,
pedro

well, I didn't have any help on this...
so I found this site:
www.jetecnet.com

where they sell all kinds of service manuals and I bought a version of
the tek2225 service manual here, for something like $10... good
service, payment by paypal, quick delivery.
