Re: [Phys-l] Advice from a veteran teacher?

[Peter Schoch <pschoch@nac.net>]

The scope is for electronics, and is probably WWII surplus -- I had  
3.  They generally work well when warmed up, but don't bet on getting  
parts!

HOWEVER, don't throw things away!  Contact a local antiquarian!  I  
donated/sold much of my very old equipment to local amateur radio  
people, and got a fair chunk of money from the antiquarians for the  
other stuff so that I could then go out and purchase some new stuff.
