I picked up a massive tectronics tube scope from a local army surplus store
for 50$. It was pristine. I like it so much I bought the other one they had.

I wanted a tube scope for the Tesla Lab--such as it is--because they are
less sensitive to being fried by the coils output. I don't have to stash it
during firing like I do my Tenma sig gen freq counter.

Hi Robert,

I remember them and I looked at many.  The conversion was expensive and
"rough".  The result was very poor by any standard.  If you want a nice
scope cheap, just go to ebay.  I think the going average price is less than
$50 there.  Even the like new super scopes are hardly over $500.  Some
perfectly good older simple scopes are at only $10.00 (shipping will cost
more than the scope).  Try to get one with probes since a nice probe will
probably cost more than the scope ;-))  It is not worth considering
anything else unless you want a "project".  Scopes these days are
practically free if you look around.  We have $10000 scopes we bought only
a few years ago that we use as monitor stands now...

Little scopes like this are a dime a dozen...

If you want a project.  Get a nice broken on like this for $1 and see if
you can fix it:

Most of the time they just didn't know how to work it and it really does
work fine. (intensity turned down, normal mode without a trigger signal,
level turn up so trace is off screen...)  E-bay often has manuals and parts
too!

It must kill people who have a scope they paid $5000 for that goes for $20
on E-bay :o)))

Cheers,

	Terry
