Hi All,

	I just bought a cute little Tektronix model 321 scope.  It is rated to
only 5 MHz, but that's OK, since it's battery powered, and was built
before 1963 :-)).  It's all solid state, too (not sure if that's good or
bad, yet).

	Anyway, I was wondering if I could stick this thing on the inside of my
toroid for making topload current measurements, without letting out its
smoke.  I'd then view the screen from the coil's controls via binoculars
;-)).  My gut says "no", since the scope's components use the case as a
ground, and RF might make things a bit messy.  Comments???  I know I
could float it at a high DC potential, but I'm not sure about RF.

	At any rate, I'm glad that I don't need to haul my Tek 545 outside
anymore, unless I need to make high frequency measurements ;-)).  Also,
did Tektronix make any battery powered tube scopes?

Thanks,
Winston K.

PS-I got the thing for $50, because there was something wrong with it.
When I took the case off, the "problem" was that both of the horizontal
plate connections to the CRT had been disconnected!  I put them back,
and all was well :-)).
