[sdiy] Scope problem

[Jay Schwichtenberg]

Karl,

Hard to say what the problem is. Another area that could be bad is the high
voltage section of the scope. See if you can dig up a service manual and
start going through the scope. Scopes of that vintage from Tek have
good/real service manuals.

Good luck.
