None of the capacitors on the 224x power supply are known to give trouble consistently as far as I know, so you might forget about the re-capping and just see if you have those 17 diodes marked "XS".

My 465 had no trace, 8v rectifier and 1 chip was fried, replaced then I saw a dot. Sent on the TELUS Mobility network with BlackBerry

yeah, not likely to be grumbling i paid too much for it while working on it :-) though it did cost me a gallon or 2 of gas. phil

thanks for the tip. i did not know tantalums smelled. i'll probably hit big filter caps anyway...i had a bad experience with them in a 465M among other PS components. i have the service manual etc.

Hi Phil, A free 465B is a wonderful thing! From my own experiences and reading the Tekscopes group for years, maybe consider starting by checking the resistance to ground at each power supply test

This scope has been up and running for a few days now and all other functions are working. Horizontal gain is off slightly (from my time mark generator). Before I do a calibration I want to go ahead

For starters I found this on ebay but it looks too short.

Nice find, and nothing is sweeter than fixing free stuff :-)

I just picked up a 465B off Craigslist. Came with 10x probe. the ad: "Unit was working, then stored for 3 or 4 years. When I turned it on recently, it died. There's a beam, but no sweep. It worked

Hi Rich Thanks for the quick reply. That would be great news if a vendor had the cables. I have so much on my plate right now that it would be hard to add another project of making the cables.

When I first saw the relays I was shocked that Tektronix is using cheap relays for supposedly high end test equipment. Same goes for electrolytic caps.

Hi Robert: I don't think the SA/TG will completely error out, but may fail certain normalizations if you do not have the appropriate flatness. I know of a vendor who may be able to help you with

Thanks for the information, I agree with both of your assessments. It was easy to find the Cables in a flex format so I went out and bought some on day one. Now that I read your posts I know it won't

Hi Jim Thank you so much for clearing that up, I looked at 11-33 and it seems fairly easy to use my Dremel and a drill to modify the VR plate to the TG plate :) I also downloaded the firmware files

I wonder me ..What is the stuff in both ultrasonic transducer surface?. Since this levitation occur due standing wave which create nodes of high pressure followed by valley of low pressure where the

That narrows the problem down to some point at or after transistor array U460. The good news is that the 2213 does not use a custom trigger IC so if the problem can be found, it should be relatively

Kurt, ? That is a great bit of work - Thank You. ? Kind regards, DBN

Hi David, still out there? back from trip... I checked tp444: with trig on "line" i have a sinus with about 0.5V tt if i connect a 4V top-top sinus at ch1 with trig on "int" i have 150mV sinus on

"Now if only I could get the readout to reflect a 100x probe when doing tube work!" Is the 5000 series readout system different than the 7000? On the 7000 series all you need to do is have 6.2K +- 5%
