Hi Guys,<P>I just picked up this 'scope. Pretty good for its age-- has a clean, stable trace.<P>Problem is that when rotating the horiz. amplitude control clockwise the trace goes off the screen to the right. I have to use the horiz. pos. control to bring it back. The dc balance has no effect.<P>Any thoughts on what to look for when I dig into this thing?<P>Thanks, <P>------------------<BR>Dave Augustine KC8RKC
