Re: WTD: 7704A Power Supply
As far as I know (which doesn't go very far), all the 7K scopes used the same connector system. I've never seen one with a conventional PCB connector for instance. A trait I like about the 7K

On screen display and other CRT items....
The "ripple" in the on screen display function of the Tek 7K frames was a deliberate thing. It was used to prevent phosphor burn by moving the display around slightly, enough to prevent phosphor burn,

Re: TM500/5000 and 5000 series scopes
Walter, don't forget the military's definition of "portable": it has handles. Most folks argue about the portability of a 555 or 556. Still, the TM506, fully loaded, was a darned sight lighter and

Re: CT501 for a TM500-seried power module
Thanks, guys. I was having a senior moment. "Lemo connector" used to just roll off my lips when I worked for Tek. A very-finely machined component that's a pleasure to use. And it's the 4-pin version

Hi, I recently bought a 7504A mainframe with a note saying that it's electrically perfect but has some loose contacts on the contact strips for the plugin modules. I haven't had time to do anything

Re: WTB: Tektronix 7D01 w/DF1(or DF2)
Hi Craig and the group, Yes, I know... but I prefer a seller who can check it and says something different to 'as-is' or 'not checked' or 'I don't know how it works but guaranteed not DOA' ;-)

WTB: Tektronix 7D01 w/DF1(or DF2)
Good morning! Title says it all ;-). I want just the plug-ins (no probes needed). Please, state condition (physical and operating) and price. A service and / or user's manual would be a plus. Thanks!

Re: Info: 564B found FS in Wollongong, Australia
Er - OK, Wollongong is in Australia, right? So $165 is Aussie dollars? That would make it around $80US or around ?60UK. At that price, I'd snap it up. If I wasn't on the other side of the planet, that

Re: WTD: 7704A Power Supply
Funny you should mention that. It is a long time since I used a 4-bay Tek scope, but I recall that the readout vibrated up and down a little too (it was either a 7704 or a 7904 - I forget which now).

Re: WTD: 7704A Power Supply
My 2 cents: Sounds like you're so close now to having it fixed, I would think you'd want to take the last steps. You've narrowed it down to cracked or missing backplane connector shells. This is

Re: Digitizer on eBay
Stan I forget to look for a part number. What you said sounds right to me. I like the idea of a coaxial relay. Are they used in anything else? I'll probably be asking about pinouts later. Thanks.
