The Tektronix video that David Holland linked in his post ( https://www.antiqueradios.com/forums//viewtopic.php?f=6&t=192722 ) mentions a key point which is to apply the soldering iron tip to the

If you go to the Elektor site you will find a download link that shows a view of the cover and of the table of contents. Tom

Congratulations Gianni, Your skill and dedication has been evident from the very first pdf you made available here. Great content and equally great quality of design of the pages. Now that hard work

We Use Metcal Smartheat iron. Use ONLY silver 2..3% solder icluded inside scope. Check serv manual for tip temp recommendations. DO NOT OVERHEAT! easy to crack ceramic. Good luck, Jon

THe book looks great! Can you tell us a little about it (table of contents?) When will it be shipping. Do you know if they will ship to the U.S? Can’t wait to read it! Grayson KJ7UM Check out

Hello rivet_head, Yes, it gives me satisfaction to have made this little card that I sell all over the world. The last TDSs I found were all without Option 013, I'm also sorry about the

When we closed up our assembly department, my old boss gifted me an entire box of the Hexacon stick irons shown in the video. All brand new in boxes, spare elements, the whole deal. They may not be

I don't know. It was just something that occurred to me out of the mists of time since I've made the mistake of putting a TM-50x plug-in that requires a high-power compartment in a non-high-power

Thanks all for the pointers. Yes, I knew about the silver solder thing. Have a spool of Radio Shack branded stuff purchased when there were still retail stores. Looks like I’ll have to upgrade the

I don't suppose I'll be the only one to offer this information, but Tekwiki states that the TM-515 does _not_ have a high-power bay, but if a PS-505 is put into a standard-power bay, it is limited to

Hi Guys, thanks to the trust of Elektor, one of the best known electronics editors, with my immense joy, a book of mine became reality... I mean: a real book, in real paper, not just a pdf file. I am

A TM-515 is certainly worth having. I forget whether it has a"high power" slot like the TM-504/6 mainframes, but in any case my first thought was that a PS-505-1 needs to be in a high power slot or

Hi Barry, It should be not too difficult to check whether or not the incoming signal at R4470 is affected by vertical position changes. I tried this (and saw no effect, of course) viewing and

Oh, man- if I was closer, I'd grab it in a heartbeat, but I'm in the bay area! -Dave

Yes, this TM515 portable TM500 series mainframe has to go. Now, it's not working properly, but you can have it free if you're willing to pick it up at my place in Laguna Hills, California, USA. I

Apparently P312 (+/- 17V connections from the regulator board to the rectifier board) wasn't making connection to the +17V side. I checked the voltage at the test point and it was virtually 0V but

Without the silver, the solder de-bonds from the ceramic. As Ed Breya pointed out, that doesn't necessarily mean that the electrical connection between components will fail -- they can still remain

What does it look like when they're ruined that way? I don't think I've ever seen that damage before. I'm guilty of adding just a bit of regular solder to a terminal or two many years ago for a

Standard Tek Svc Ctr issue in the mid 70's was a 60 W Hexacon fpr strips and a tiny Antex for PC work. -ls-

I have definitely ruined a few ceramic terminals due to silver depletion. It only took four or five heatings with standard solder. I was using the same model Weller WTCP that Tek issued me when I
