content: I would like to start this thread rolling with a greatTEK troubleshooting PDFthat should be had by anyone with a CRT scope.http://www.sphere.bc.ca/test/tek-parts/troubleshooting-scopes.pdfNotewww.sphere.bc.cais a good source for Tek and other scope parts.Here's a x reference pdf for Tek parts:http://bee.mif.pg.gda.pl/ciasteczkowypotwor/Tek/publikacje/Common_Design_Parts_Catalog_Semiconductors.pdfThere's another here:http://www.sphere.bc.ca/test/tekequiv.htmlBut the best one is at the foot of that page. Sphere ask that it not be linked so you can find it yourself and download it for reference. Be warned, it's a zipped PDF 27 Mb.For all things Tek:http://w140.com/tekwiki/wiki/Main_PageIf you have something to contribute and you can't provide a link, post a quick description and attach it in a format the forum allows.By all means re-visit to edit links and posts to keep this a great resource for the future.Thanks EEVbloggers.See how this thread goes, but I would hope that content is primarily documents and links.For newbies opening repair threads:Use the following posted links to find a service manual for your broken equipment and be sure to include that link into your thread so we can all play along and help easily.

content: I've been searching all over the net for any Intron DSO-2020A documents (schematics if possible) but it seems too old to have any available although someone in an other forum said they had some in 2008. Not sure if i'd dig up the topic again...The only thing i found is a reference to the older model here:http://www.radiomuseum.org/r/intron_storage_oscilloscope_dso.html and a picture of the one I have here :http://www.radiomuseum.org/r/intron_digital_storage_oscilloscope_dso_2020a.html#bFun fact, the one I have has the CRT cover of the DSO-2000... I think someone tinkered with it before I got my hands on it and decided to have a laugh but since they both use the same CRT model, it doesn't surprise me that much.Anyway, it powers up and I get the trigger led to light when tinkering with the knobs but the screen remains silent. I haven't tested it any further yet but I'm sure I'll find something bad in there.Anyway, I'd be happy if someone could point me in the right direction for the docs. Is there a website for really old stuff ? The links provided in the previous posts don't list any Intron stuff like they don't exist. I have to say though that this scope was made in the Netherlands according to the back plate.

content: Not sure if this is the right place to post to but....Looking for the schematic/circuit for a Vision Engineering Alpha Microscope PSU main PCB.I salvaged a much used and abandoned microscope for home use.Initially the lamps were flickering at about 2Hz which I cured by replacing the main Electrolytic, but now at power up, the circuit takes several attempts to ramp up to full light level.I have gathered up data sheets for the ICs and I am hoping that someone has a schematic/circuit diagram before I have to trace out the board.I believe the problem area is the Triac (MAC223A-8-ON) driven by a Zilog (Z86E0412PSC) that produces the lamp level PWM?, so anyone with experience of this type of circuit I would appreciate hearing from you.I have yet to start probing the board with my scope, but this will be my first use of it, so I am doing a lot of reading up before I start poking into a live board.Thanks in anticipation.

So while I continue my search, might someone, anyone here have any docs on this gadget? It's VERY well built, but is off freq a bit and I can only walk it in to within about +15hz of "on freq".And as always, thank you.

Couldn't find anything in the internet about the existence of such a modelAll the PCBs inside look OK, non of the capacitors seem to have leaked at least from a visual inspection. However rats have chewed on almost all the inter-board wires.If anyone has any information on this specific model or something similar, That would be highly appreciated. A repair manual or a schematic would be a godsend. Thanks in advance.IT's a Yokogawa 3663 CRT oscilloscope, 100MHz 2Channels

I ordered a download two weeks ago and it did not arrive so I called and was shocked to hear that Dave, the guy behind it has died over Easter. His wife, Linda, is trying to keep everything up but she was never shown through the operation of the web site. For now, do not expect to get downloads. She is fulfilling CD orders. She is hoping to get the downloads working but is not sure how long that will take. For now do not expect to get a download from them. Just order CD's.artekmanuals.com

I tried emailing them and got no response, and I tried calling and the number was disconnected.My fear was that the owner had died in the couple of weeks inbetween my two orders, but I see he sadly died 2 years ago. Is anyone here in touch with the person currently running it? Is it still his wife?
