scopes [was: how to troubleshoot? ...]

[harry]

I did a "Lasera" type show using my modular and XYZ scope...
in the mid 70's.  It was not bright enough... but very cool to
watch !

Also did the same with a modular and stereo amp, 4 speakers, a front
surface mirror, and a laser.

I was almost as loud as the jazz band (big) who was trying to drown ME
out.

So it is ON-T after all
