Bill, when you go hamfesting, look for an old book
titled "101 Ways to Use Your Oscilloscope."  There is
also another in this series called (guess what) "101
Ways to Use Your VOM and VTVM."  These were put out by
Howard W. Sams, I think.

You might also find them on that auction site we
aren't supposed to mention aloud (sshhhhh).

When you are looking for test gear, I highly recommend
Eico equipment.  The Model 460 scope is a 5 inch unit
and is very useful and reliable with a bandwidth
usable from DC to 10 MHz.  Sure, there are better
scopes but you can actually repair an Eico if it goes
bad -- try that with a Tektronix and see what it ends
up costing you (cheaper to buy another one and use
that till it breaks).  I also highly recommend the
Eico 232 and 249 VTVMs.  Be sure to get the
"Uni-probe" with either one if you can.  

All this gear is a dime-a-dozen on that (sshhhhh)
auction site, along with the excellent Eico 324 signal
generator which covers about 150 KHz to 170 MHz.  It
does not have a calibrated attenuator like the
mil-spec generators (URM-25 etc, and I have one of
those and it's indeed fantastic) but it is just fine
for general servicing.

Eico also made a very nice capacitor tester/resistance
bridge, the 950; and a neat Model 147 signal tracer.
And the 710 grid dip meter (be sure to get all the
coils!) is excellent as well.

Heathkit made "clones" of many of the Eico units (that
is, copies) but in general they aren't quite as nice
as the Eico.  All the Heath stuff (and Knight) was
built in somebody's garage or kitchen.  Eico was sold
in kit form, but much Eico gear will have been factory
wired and has come out of TV serivce shops or, even
more so, tech school labs where it was well cared for.
