Anyone have a source for a service manual for a Tenma 72-905 O'scope?
I have one that the horizontal trace stays on the left side of the
tube only. Figure it's a problem with the sweep circuit. Anyone seen
this?

With the power off check cold, initially, for differences between the 2
final X-drive transistors, usually long-tail paired.
