Re: Use a scope to determineovervoltageneededforstepper motors

More commonly refered to as a Boatanchor, last cataloged
in 1971, 15mhz bandwidth. There is nothing better than
working on old tube radio's, together with old tube test
equipment, heck I us my old 545B on my cnc stuff. Its
big, heavy and power hungry, but has features some new
scopes do not.

Bob, this is a relic. My guess is from late 50's to early 60's. I used an
RM-515 in the Air Force in the early 60's. I
suspect it is only about a 15 - 20 MHz scope.
