Thanks Stan for the insight. Very interesting! Regarding the 455 BW, I also recollect the T935A scopes I worked on usually did between 50 and 60MHz. If they did only 35MHz as spec'd, something

Hi, I live in Germany and I am collecting old Tektronix stuff. Is there a 568 with sampling plug-ins or any other sampling plug in or spectrum analyzer plug-in in this lot. I don't have any

I think that it was actually the Berg Miniserts that were the most troublesome of all the sockets. But they were so danged cute and since they were individual pins, they could be placed in any

I'm late with this, but I found over the years the most effective cleaner for goo-like substances (i.e., label adhesive) is mineral spirits. It rapidly dissolves gummy substances without attacking

I think you answered your own question below, but just didn't see it. :) -- jm

Well, Walter, that's the nice thing about this world. Everybody's different (especially those who think that hp made the best scopes, although I did much prefer their 130C over the Tek 503) and

Everybody seems to have missed the entire point of the 465M, it was designed specifically for a MTTR of 30 minutes, and the modular design makes that possible. The MTTR of a regular 465 is measured

As much as I like sockets, I must agree with Dean. It is sure handy to be able to remove and replace components easily, but that should be confined to prototyping. The first Tektronix scope that I

John, with no manual, it's difficult. Since intermittents are a big problem with Tek products having socketed component, the first thing I'd do is rock every transistor around in its socket.

Don, that is a T912 in the ebay photo, and it is a dual-channel, single-timebase, bistable storage scope with a bandwidth of 10MHz. The T921 was the least-expensive, but didn't didn't sell very

I'm not sure I've figured out how to reply on this forum yet. I'd replied previously to the #445 OP as I am now "465M Flaky vertical height" figuring that it would end up in the queue at the end,

Don, Thanks for the picture and descriptions. This is not the scope I used. The one I used had the Telequipment name on it. It was horizontally layed out. The tube was on the left, then the

I have a Tek 2232 scope and am looking to add the RS232 plot output. Tek apparently offered a field installation kit (Option F12) however apparently neither the kits or tech support is available

Hi Doug, There is a photo of a T912 on ebay at: http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1622982027 The style is similar on all the T900 scopes. Blue plastic case, tube to upper
