I haven't ever looked at a 7100 scope, but I did have a 7904 with a very dim readout. If you turned the trace intensity all the way down and dimmed the lights, you could make out the readout

Hello, I have been pulling problems out of a 465 that I recently acquired. The last remaining problem is the inability to get a sharp focus on the trace with any combination of intensity, focus or

Just a little poll of sorts: I'm wondering where we all find old equipment -- at least the stuff we get for real cheap! I and a friend on this list have found pretty much all our stuff at "garage

I paid 25 for the 545a, most of the plugins cost 15 to 20, bought one on ebay as well as some of my manuals, some of the stuff is in a salvage yard, near by, but they run 25 to 45 dollars depending on

Gee, half your luck! I've never seen any Tek stuff at garage sales (not that I go to many), and paid A$600 (around US$1200) for my (as new) 7603; but I was given a TM503 with a DM501A (faulty) and

I started my collection with a 535a that I purchased at a garage sale for $1. The scope came with CA plug-in and a set of probes. I always admired the Tek scopes from the 60's and thought that it

old stuff Hello Michael, and thanks for helping me get past the sign-on glitch. As you can see, posting now works too [I think - we'll see]. I started accumulating Teks (beyond a couple for use) ~

Hi Mark, Yeah I remember posting a list of the YaHoo groups I belong to. I know what you mean about the older scopes and their fine trace lines. My old 453 is still on of my favorites, I can sync it

Does anyone know where I can pick up the GPIB OPT 10 for the Tek 2230 or the RS232 option? Thanks, Vince Coppola

I believe you're right, Stan. I'd heard both explanations. Actually, the geometry story doesn't pan out well if you've ever seen one of the guns outside of the jug. the mesh is hemispherical

Does anyone happen to have a Service Manual for the Tek 2230, they would like to sell? And does anyone know what the power up error: CDT : uncaled : min = 84 might be about. Thanks in

Stan, Yeah, try to get most people to agree that the addition of the engine computer on a car was a step forward. I think the step forward was the fact that I have yet to not have a computerized car

I have a friend who has an electron microscope -- if anyone cares to lend me a bit of mesh, I'd be glad to get pictures of it and post them. Naturally, I'd return the mesh too if you like. -- John
