Dumont 1062 scope

[Paul Degneau]

I have a Dumont model 1062 oscilloscope that I bought recently at a swap
fest. The previous owner had no manuals or anything for the scope, I
managed to rig a power cord and get probes for it, but I would like to get
the manuals for it. If anyone knows where I can get the user/service
manuals for this scope please reply to the group or email me.

Also this scope seems to have a vertical and/or preamp problem. Channel 1
is slightly fuzzy but seems to be accurate, channel 2 is very clear but the
vertical size of a trace varies depending on were it is vertically on the
screen. If anyone knows what may be wrong I would appreciate any info.

Thanks,
Paul Degneau

I purchased the same scope again with no manuals. I know it works, I just can't set it up to get a reading on anything. Searching the web now. I would appreciate any advise. Anybody feel free to email me or send any helpful links.

thanks

>I know it works,

How do you know it works? Can you see a trace? Can you see anything
on the screen? Is it a line, blob, or a smear? Does the beam finder
work? Or do you know it works because the guy who sold it to you told
you that it works? Caveat Emptor.

What do you mean by "reading"? I believe the correct term is that you
can't see a trace or waveform display.

Well, I can't offer any suggestions unless you disclose what you're
seeing on the screen. We can then precede from there.

Hint: Anything that old is going to have problems with "dry"
electrolytic capacitors. Have they been tested with an ESR meter or
hopefully replaced?

i good one of those scopes, I was just moving it today actually trying
to clean up the shop with very little luck I may add.

The last time I used that one I know it worked but I had to repair it
once. The HV multiplier failed and there was no parts for it so I used a
ECG replacement HV multiplier for TVs, wrapped it with foil and jammed
it in there :) It works, I can't say that it has caused any side
effects..

I suppose if some one was willing to pay the shipping I could let it go
:)

I recently picked up a Dumont scope type 2559a serial # 1252
Looks really cool and the thing weighs like 100 lbs.
Anyway I was playing with it over the holidays and it seems to be reading vertically on the screen instead of horizontally like a normal scope. Anyone ever heard of or seen that before? Any ideas?

That's good; so if you strap your ankle to it with a flexible linkage,
you get protection in those situations where an electric arc would
otherwise throw you across the room.

There's a manual on ebay for pretty cheap.

This is a late 1950's scope so most that ever used one have forgotten about
them.

Possibly somebody swapped the wires on the deflection plates. Usually there
are 4 wires poking out through holes in the CRT magnetic shield, with wires
to the deflection amps. You could try swapping the pairs of wires.

Just because you have something to say doesn't mean you should reply to a
17 year old thread, even if it was resurrected last year.

If you have something to say, say it, don't reply to a really old post.

This was isn't even the same model as someone was asking about before.

Take it out of the case, it will likely be a lot lighter (though more
dangerous), that was the case with my first scope I got in 1972 at a ham
club auction for five dollars, barely able to cover audio frequencies and
no triggered sweep, it was a cheap way to play with an oscilliscope.

When I got something better, a friend took it, getting it home on the bus.
I can't believe it.

With usenet being what it is, there are posts being recycled with new
dates as people shift servers.........perhaps they think they're doing
you a favor.

Unless you read the headers, it's not always obvious.

I'm seeing my old posts showing up from as far back as Y2K, with new
poster names and date.

That doesn't matter at all because the posting doesn't quote any of that
article. The only clue that it's a followup is the References: header
and the "Re: " prefix in the subject line.

Take away those, and you would have no clue it's a follow-up to
anything old.

I totally agree. Google should show this tip when people get on it to access Usenet. Reason ? Others might have to wade through hundreds of posts to get to the meat of things. And as you said, the thread title does not even mention the necromancer's model number. How is anyone else going to find it ?

I hope all the Googlesters read this and get with it but they won't. Even if they do, more will come.

Actually I was here for the OP, but under a different domain and did not comment. Actually some old scopes did have a switch to interpolate X with Y. Rare, but I saw them. You could also do that with a bunch of Teks that used plugins, I have done it on the 7000 series just for fun.

Anyway, in this case I think there is no horizontal sweep and seeing the vertical witho9ut that gives the impression it is turned. Really, how the hell would that happen ?

The way to tell is with the position controls. What happens when you turn those ?
