Re: (OT) Curious about DuMont Type 233 Giant Screen Oscillograph
Just looked it up....that is indeed a thing of beauty. The only -hp- scope I own is a 1727A storage scope (a very nice instrument in it's own right), but that 143A is super awesome. Maybe

Re: (OT) Curious about DuMont Type 233 Giant Screen Oscillograph
One of my prized possessions was the HP 143A Oscilloscope mainframe, which took the various RF and IF spectrum analyzer sections that the 141 took. The screen was 8 x 10 inches, instead of cm.

Re: (OT) Curious about DuMont Type 233 Giant Screen Oscillograph
Interesting. Are there any scans of that datasheet?
Good luck finding one...my gut feeling says that if any exist it'll be in someone's estate.

Re: (OT) Curious about DuMont Type 233 Giant Screen Oscillograph
I've been looking for one of those for years. Never came across anything other than a couple of ads in some old magazines and I have a 4 page data sheet from 1943. It used a 20AP1 CRT, frequency

Tektronix 7904 Blanking Problem
My 7904 has developed a blanking problem. The CRT screen shows the beam spot as it flies back at the end of each scan. A quick look at OCR'ed manual find some discussion on "Horizontal Chopped

(OT) Curious about DuMont Type 233 Giant Screen Oscillograph
Hi all,
Sorry for the OT, but figure this is a good place to ask.
This is more of a curiousity thing for me...I don't have room for one of these 350 lb behemoths if one was still in existence and

Hello Chuck,
Would you consider investigating reasonable shipping costs to near Melbourne Australia.

OT, but wow, the work you put into those pre-war TV restoration jobs is
impressive. Beautiful results. It must be a full-time job just to
coordinate all of the cabinet work, transformer winding,

7104's are fantastic. I have 3, and each was handled by high level experts
who never abused them. The micro-channel CRT really lives up to the claims.

If anyone is still looking for a 7104, I found one in my storage building. It works well CRT is bright with 7A29, 7A29 opt 4, 7B15, 7B92A. Looked all over for a 7B10 but don't have one.
I really don't
