This one has bothered me for a while. Sometimes the height will be about 50%
of normal on either channel. Very intermittent. If I put the unit in chop
and run the other channels position to very high or low on the screen, the
offending channel will 'pop' back to correct size. At one point I could tap
around the funny heatsinked hybrid in the vertical section and get it to
fail. Removed IC and cleaned the contacts with Qtip and Deoxit and it worked
for a while but then came back. Has classic symptoms of bad connection but I
can't seem to get it to fail often enough yet. Any shortcuts?
Note this scope appears to be quite different from 465 regular-flavor (at
least vert section).
Thanks
