So, I recently got a Tektronics 545B oscilloscope. It's been sitting in a
basement for god knows how long, and I thought it would be cool to see if it
worked. well, it doesn't. It's missing it's fuse and fusecap, and it's power
cable. I had read in a couple of places that the fuse only affected the high
voltage stuff, like the CRT. I might be totally wrong about this, which is
why I'm asking you guys
Well, with that in mind, I found a newer power
cable that seemed to fit the bill, so I tried using that. Nothing. I then
tried using a voltage regulator. Still nothing. Now, I'm not sure if it's
because of the mysterious missing fuse, or if something else has gone bad
inside, or if it was the power cable (which I doubt). My next guess was that
it was the missing fuse. Holy crap does this thing have a strange fuse. I've
looked all over for something with a similar rating and size, but with no
luck. I'm not as worried about the fusecap. I searched for a couple weeks
online, but I eventually came to the conclusion that the thing would
probably never work. Today though, I thought I'd give it a go again.

I opened it up to find TONS of gunk and dusk blanketing it's insides. I also
found a pdf of its manual (which has slightly more info about the missing
fuse). Now I think I got in over my head, because I'm too scared to touch
anything. Before I go fiddling with 50 year old electrical components, I
want to know if it works or not, what I can do to fix the fuse situation
(even if only temporarily), and if I should check for anything else.
So, can anyone help me? I'd REALLY like to get this guy working again, but I
need some help (obviously, hehe...)

There is a Yahoo group dedicated to the old Tektronix scopes. Why don't you
join it and ask there?
http://tech.groups.yahoo.com/group/TekScopes/
Over 6000 members, sure to be someone that can lend you some guidance.
The usual way to clean these scopes out is with soap and hot water. That
subject is covered on the group.
