Thanks to everyone who has emailed the list with suggestions for me to try
to cure my ailing scope. I have a copy of the service manual and have taken
a look at the various schematics. To say I'm intimated is an
understatement. Just looking at the voltages coming out of this unit scares
me. I am just starting out on this electronics hobby path, and spend my
time playing with low voltage DC circuits. To be honest, I'm not even sure
how to go about checking the voltage within the unit, and forget about
techniques to determine ripple on the supply. I have trouble really
understanding what is going on in a typical RC circuit, and that's just
running off a nine-volt battery. I'm afraid this one is over my head. It's
a shame as I really like the scope, and I'm finally in a position with my
family life that I can start fiddling with it. The scope had been in
storage for about a year as I focused on my family and work.
Again, thanks to everyone who gave some practical suggestions. I will file
them away. And if I can't find someone who has experience with these scopes
and who can take a look at it, then, one day, when I feel more confident
playing with high-voltage equipment, I might drag it out and see about
repairing it.
OK, back to my lurking status.
Kevin
