Hi, Would the person that responded back to my message concerning the communication options for the TEK 2230 please respond again. I can't seem to find your message. Thank

I hate to disagree with Stan, but my experience with 7A16Ps is that if you install them in a non-programmable mainframe, they power up OK, but the front panel is locked out. From looking at the

Thanks all, for your replies to my question... Kind regards, :) Michael

I have the start of a Tek interest site : www.vaxxine.com/phil/ Phil Turcotte Grimsby, Ont.

I would ask again that anyone who wishes to can place a URL link to their site in the LINKS section of the TekScopes Yahoo site. Also, people who have parts etc to sell, but DON'T have a web site,

Hi Bob, There is some possible incompatibility using the 7A16P in a normal 7K mainframe such as the 7704A. The 7A16P was specifically made to be used with the 7912AD digitizer and is programmable

As I recall, the reason Tek would not recommend a 7B53 as a timebase for a 7704 is that it will not sweep fast enough to take full advantage of the 7704's 200 MHz bandpass. Other than that, I believe

Hi all, :) A couple of times recently there have been mentions of people who hold some stocks of Tek parts for sale for replacements. (e.g. pots, transistors, tubes etc). After a recent rebuild

Yes, that's what I was talking about... I know it's written up in one of the manuals or catalogs, but I can't seem to locate it at the moment. I guess I'm just picky :-) On the other hand, 7B8xs are

bandwidth 7B53A's And Seconded - before I acquired 7B87, later -92As via a package deal: a 7B53 in my 7854 (400 MHz nom) scope worked fine. At fastest sweeps, with a known ~700 pS risetime pulse

The pot/switch for the CAL/VAR volts on Ch1 of my 2230 is disfunctional and there is no detent. Manual says 311-2218-00 Tek part number, but it describes it as an Allen bradley 10K pot with

There's not a darned thing wrong with using a 7B53A in a 7704 or 7704A. It's the 7B92/A that you can't easily use on lower bandwidth scopes only because they can't handle the faster sweeps. And

The 7B53/7B53A is not recommended for use in the 7704/7704A. I don't remember why, but I think it was a good reason. The original poster needs to find a 7B70+7B71, 7B80+7B85, or 7B92/7B92A.

Good Evening I have a 7704A mainframe that is in need of repair. I turned it on this morning after not having been powered up for about 2 years. The trace was moving around erratically. Then I

Bill, if you don't mind knobs that aren't perfect, I have enough used ones to set up. They may be cracked, have a soldering iron ding, have some paint rubbed off, but they're serviceable. When I

Hello, Would anyone have a vertical output hybrid for a 7844? Tek part 155-0064 I believe... If anyone has a 7844, I can email them the necessary pictorial info where the part is and how to remove it
