Re: [OT] Best glue to repair lifted trace?
Again.... the solder connection is in place. it's just in air. It needs to be glued down.

Re: [OT] Best glue to repair lifted trace?
What do you guys think of the DIP Tools Klebefix? (mentioned in my last email). Has anyone here used it? Thanks.

Re: [OT] Best glue to repair lifted trace?
Thanks. I checked them out. I wasn't able to find a place that actually sells them - do you have a lead? It needs to be in Europe because importing chemicals from outside Europe is pretty much

Re: Things not clear to me in the 2465 calibration manual
Hi Leo, Open the calibration section of the manual, and start from the beginning, with power supply verification and adjustments. Continue from that page to the next to the next until you are done.

Take a look at these: https://www.masterbond.com/properties/high-temperature-resistant-bonding-sealing-and-coating-compounds All of them are rated to above the eutectic of lead tin solder.

Re: 1502 HV problem
1502s have a shorting bar inside the BNC connector, specifically to discharge such static charges. That gives rise to "short circuit" traces such as

Sorry - bum steer. The type 284 tunnel diode is the same as in the 7T11. Duur Craig

FWIW it is also used in the 7T11 sampling timebase. Craig

Re: Calibration and full checkout needed - Tek 7000 series
As Harvey says, a 465 would be a good analog choice. The 468 not only is an improved 465 (actually, a 465B), but it adds a digital mode. Depending on the frequencies involved in your "vintage radio

Re: 1502 HV problem
There is supposed to be a Russian substitute for the 20mA diode. My notes show it as 1i308e/Gi308e but I have never been able to find one. The 10mA one can be replaced with a AI201V, which isn't hard

I have tried CA glue on a lifted pad.? It stuck at first but failed immediately when barely touched with a soldering iron.? In your case the continuity is already there and you might risk not

Re: [OT] Best glue to repair lifted trace?
I think you made up your mind. Don't breath the fumes when you solder near ca, or get them in your eyes.

Re: 1502 HV problem
Harvey, I need to visit you one day, before the sales you go to, so I can find me some of these DEALS! It's fun to, it is like a "BOX OF CHOCOLATES, you never know what you gonna get".
