Re: Tek tubes for sale 154-0630-10 & 154-0566-00
Yes, please send his name and e-mail Peter. I lost touch with a guy - I think his name was Nick - that had a bunch of Tek crt's. Maybe it's the same guy. Thanks....Phil

Re: 2235 Bad CRT
It's a bit of a long shot, but try Tucker Electronics (http://www.tucker.com). They occasionally sell replacement CRTs for Tek and HP instruments. -- jm

Re: 2235 Bad CRT
Looking at your auction link then trying the same on this scope with sine wave gave me the answer. the 2 scopes are wounded cousins.... Seller is trying to find a tube. I'd like to keep it as it's

Re: 2235 Bad CRT
The key point is that damage to the mu-metal shield will NOT cause a magnetic anomaly to appear on the screen -- it will only impair the shield's ability to keep external fields out. If your visual

Re: 2235 Bad CRT
I'm not at all sure how many ergs you have to transmit locally; I recall that we deemed the smaller ones - used around photomultiplier tubes - to be "rather fragile" = not to be dropped on floor

Tek 585
Thanks to all which replied to my inquiry on the "auto-trigger" problem with Tek 585. There seems to be no logical technical reason for that. Urs

Re: 2235 Bad CRT
I do not claim to know it as a fact, but it seems to me that a blow that would upset crystal lattice of Mu metal, i.e. wreck annealing, would break a lot of other components, too. Having a magnet do

Re: Sources for Terminations
When I was in the Navy in the mid-1970's, we would order the 011-0049- 00 using the FSN. Amazing what the military can do to you when they decide to get something cheaper. We didn't get Tek

Re: 2235 Bad CRT
Thanks for the replies. Other than that, scope is in perfect cosmetic condition. Guessing switches should be a little noisy from dis-use, but don't appear to be. Shield on this unit is pretty

Re: 2235 Bad CRT
Hmmm - dropped you say? Mu metal shield around CRT. It was annealed at birth. Dunno chracteristics of Tek's exact choices but do recall: these shields cannot stand a large blow to metal. Just

Re: 2235 Bad CRT
It was probably dropped. I assume a sine-wave display looks like the 485 I sold on ebay awhile back: http://209.95.122.40/jm/485bad.html ... if so, that's the problem. Nothing you can do about it,

Hello New to the list Purchased a TEK 2235M with low hours on it and it has a strange problem. With input grounded, moving trace up and down, either trace distorts. When trace is at the top, the

Re: Coax BNC Cable Termination
The midnight oil that would have been spared if you used sinewave would have been spent on debugging problem coming from jitter of sinewave clock, so I do not think that you have anything to
