I Havve just aquired a 2465 300MHz scope. When i first power up all tests pass, but the crt shows a very jagged display (almost as if you were seeing noise) The display notations of sweep time and

There is a decent surplus store in southern New Hampshire. Just a block from I-93. http://esssurplus.com/index.html They have a limited selection of older test equipment, and lots of interesting other

Gentlemen, I have a TM506 that works but needs new filter capacitors. The DC supply gets a lot of ripple when the TM506 is full of plug-ins, with just a couple of plug-ins it is fine. If this is if

OK... I believe I've got both web and FTP working now. Thanks to all for your patience, and special thanks to N5ZTW for spotting the fact that the web server had gone flooey. Happy tweaking.

Well, I can't seem to win at the moment. I've got the FTP server working, but now I seem to have knocked the web server off the air. I'm working on it. Hope to have it up before too much longer.

Anybody know if there are any decent surplus stores left in MA? Like where they have Tek or HP gear? Now that I work there, figured I'd ask. Also looking for a local place I could buy (and pick up) a

I wrote the following stuff about phosphors in response to question I received. I thought some of you guys might get some new info out of it, so here it is. Stan CRT Phosphors: Back in the early 60's

Thanks for the tip, Ed. Always corroborate. Tek used specific color-coded wires for the power supply lines; if "225" doesn't point to red-red-green, the label is wrong. Or the wire. Dave Wise

Hi, Gang I have a 545 (no suffix) scope, and recently had to do some trouble-shooting. One hint: when measuring d.c. voltages along the ceramic terminal strip which has the voltages labeled on the

If the surge arrestors get a voltage higher than 230V then they are going to blow the fuse. Check to see what voltage the surge arrestors get to before the fuse blows by ramping up the input voltage

Hi everyone I've looked everywhere for a 442 manual and come up empty. Any ideas? Thanks.. Tad WA1FQO

Let me guess, the capacitor was a RIFA cap? Every Tek scope that I have seen and have checked the X class suppression capacitors on has at least shown fracture marks in the epoxy coating if it was of
