Tektronix RM-45A scope query

[W. Kranitz]

Hi,

I have a RM-45 and a RM-35. These appear to be electrically equiv.. to
the 545/535.
They're even covered in the same manual (which is about an inch thick).

Looking at the parts list there appears to be:

9 - NE-2 neon bulbs

at least 54 - tubes

and a T54P2/5BHP2 CRT


It definitely is a boatanchor. There's a guy out in Oregon that was a
Tektronix
engineer, and now supplies parts and info for all these units. I don't
remember
his name (I'll see if I can find it), however maybe someone else on this
list knows
it.


Contact me by email and I'll see what info I can give you.
