I'm in the process of thinning my "stuff" collection. I have a number of CRTs
I would like to find a home for. Some are Tex, some HP, and some just generic
CRTs. I got these many years ago from a service shop closing down, so I don't
know the exact condition of any of them. Although my notes below indicate some
appear to be new.
I'm located in Southern New Hampshire, and they are free to the first person
arriving to pick them up.
Here are my notes on the CRTs:
1 Tek Tube markings: 5BGP2, 1-42764, 5-9, P-8660; epoxied base
Box: 154-0175-00 T5430-2 (incorrect markings for tube)
round 513, 531, 535 (retrofit to 535A)
4 Tek Tube Markings: 154-0659-10, 49-3, 65458, 520, N38
This has a 6x10 grid, with an 8x8 grid overlaid. It also
has vertical markings for 0% to 100%.
Box: 154-0659-10 14-8 Apr 10 78
rect 7623, R7623 (early B010100-B010144, later?)
7 Tek Tube Markings: 154-0513-00, 24-5, 7353, 517-P-90
This has what appears to be a vectorscope *grid* on the screen.
Slight burn in the center.
Box: 154-0513-00 Dec 10 1990
round 520, 520A, R520, R520A
8 Tek Tube Markings: 154-0098-00, T0540-2, 33-6, 50555, 206 P2
Box: 154-0081-88 T0510-2 (incorrect markings for tube)
rect 541, 545, R541, R545
9 Tek Tube Markings: 36-0, 54F2, 54-69996, scratched screen
This was double boxed, with the inner box having the
markings: 51P2-154081
round 513, 531, 535, R531, R535 (retrofit to 535A?)
12 Amperex Tube Markings: D14-251GM
Philips Yoke: 2 wire (yellow/yellow) yoke
Box: D15-251GM/A
rect
13 HP Tube Markings: 5083-5861 serial number 422168
Box: Tek 154-0613-00 44-9 4815 (tube appears to be used)
rect
14 United Tube Markings: 5AQP31A 7416
Box: United E.T.C. 5AQP31A

Re: How to fix broken HP key
Imagine that some of us don't have perfect memory, and although we have read the entire thread, its details were softened as the thread dribbled in over several days (weeks?). Me personally, I read the posts as they come into my email, and if one interests me, and I think I have something to contribute, I reply to the post/email. I really have no interest in treating this as seriously as one might a vocation. Also, when posters cannot be bothered to quote what they are responding to, it makes it very hard to keep track of the earlier details. I suppose if this drift really bothers you *that* much, you could start your own group, and moderate the heck out of it, so drift can never occur... -Chuck Harris On Thu, 03 Jun 2021 11:52:55 -0700 "Robert G8RPI via groups.io" <robert8rpi@...> wrote: Why don't people read the thread and answer the question.
The OP does NOT have the usual missing leaf spring issue. His issue

Re: How to fix broken HP key
Hi Robert,
Yes true, but having established that and suggested frisking the box
for the missing contact, the thread drifted a bit into repairing the
busted plastic frame pictured - which may well be how the contact
escaped in the first place? - and there was then some question about
3D printing it then the spring came up and someone wanted the
dimensions and so it goes, all fair and good questions and sort of
related to the OP?
I've often wondered how to better manage the issue of thread drift
other than in retrospect and never really come up with a solution
but of course adding this sentence to my reply is thread drift.....!

75 ohm 'N' connectors do exist - but not on the front panel input of an Agilent E4411B.

Re: Advice for a new to me Spectrum Analyzer
CAREFUL - There are both 50 and 75 Ohm N connectors. Mis-mating them
results in distruction of a 75 ohm connector.

A 50 ohm instrument will have a type 'N' input connector.? A 75 ohm

Some also have IF + sweep + VGA out.

Re: How to fix broken HP key
IFF this applies and we are talking about same type switch...
below is from the EDN article re the bill west switch-dimensions of spring-
"The return spring is an elegantly simple steel leaf measuring 0.588 in. long by 0.140 in. wide by 0.002 in. thick.
A slot in one end of the switch¡¯s red plastic body captivates one end of the spring. The spring¡¯s free end fits...."

Re: How to fix broken HP key
As Chuck points out there are many threads on this.... however to get the overall dimensions I just clamped one in the 1/2" jaws of an engineers parallel clamp to prevent the afore-mentioned buckling and measured it using these new-fangled mm units with a Mitutoyo 0.001mm micrometer and got:
L=14.12mm? W= 3.65mm and T=0.055mm
which, in good old-fashioned units would translate to:
L=0.556" W=0.144" and (as Chuck says) T=0.00216"
I have found that 2 thou (AKA mil) feeler gauge (gage) stock cut with small tinsnips works just fine.

Re: - Advice for a new to me Spectrum Analyzer
Check to see if that has a 75 ohm input impedance!? (As many do. It will be marked on the front panel, or you can tell by the list of installed options.)
If so, take care what you connect to it, 75 Ohm 'N' (and other) sockets will be permanently damaged by a 50 Ohm plug.

Re: HP PN 1855-0418 Part Identification Help
Frank,
Thanks, I could buy those but the truth is that in my country we have to pay more than 100% taxes. One single FET would cost more than a whole minimum wage of salary around here. So I try to avoid importing as much as possible, but it is a possibility if I don't?find a more widely available part. Thank you for pointing me to that ad.
Vladan,
That's really valuable info. Where did you get that from? I've been googling for days and found nothing. I have been looking at a NS 2N3958 datasheet and am wondering if that would do the job. Gfs is at least double the minimum you listed, and Ciss is typically around 3.5pF, but the rest seems ok. Considering these are select parts, what exactly?did HP select them for? I'm asking because you seem to have much more information?than I ever managed to find after many days on google.?
This is a selected part, which means that something similar was widely available, but I can't give you any commercial part numbers. Here is what I have:
National Semiconductor SF83025 or Intersil ITS31087. These are custom numbers, don't bother looking for them in old catalogs. However, see if you can find something similar to the specs below in NS and Intersil books.:
BVgss 40V min
IDss?? 0.5mA min, 5mA max.
Gfs? 0.5mS min.
Vp/Vgs (threshold)? 0.5V min, 4V max
Ciss? 2pF
Vgs match? 10mV
300mW max
These are almost certainly made with two die per package.
