A bad solder connection on a Tektronix PC board ? The world as we knew it is GONE. And it was also gold plated.

When you resolder things that go intermittent you see how the solder melts, how it grabs and you can kinda tell if you REALLY had a bad connection there, I say it did. The solder seemed to want to stick to the lead or the pad, but not both. That indicated that there is some contaminant at the point of the pin that is supposed to soldered to the board. I have seen this before. The connection, with the solder "draped" across is made but in time WILL fail. Not might fail, will fail. This I deem most likely due to thermal expansion, not that it is the only factor of course.

I really want this fixed before I put it back in the unit. It is a bit of a bitch to R&R. I have to start screws and nut that I have no idea how the hell I didn't lose. So naturally I am going very slowly. I have irons out of the fire top gitch up some money, and I might even buy this. It really seems to be a decent scope and with the alt function it is like, REALLY good. Irregardless, (yes I know :-) I deem this a relatively uncommon failure.

And maybe that's why my friend got it so cheap at HGR...Actually it did have a different problem but with a missing knob, (we'll talk about that later) it got set aside, and we didn't want to sell much of anything. But things change and just how many scopes do we need ?

Anyway, I figure I will scrutinize it a couple more times. OK, Tuesday is venison day, medallions. After eating I will put it together. Before then I will have looked at it with magnifier many times.

In the meantime I got an up and coming 2225. We'll see about that later.

Just remember that saying "We'll burn that bridge when we come to it". Use that and see how many people just didn't notice what you said...

I'll be ba-a-a-a-ck. Next I am going to throw together an attenuator so I can check this thing on every setting of the vertical. Actually I have a little board with a shitload of resistors on it, precision. I can select any value from 0 - 1,111,111 ohms. And I can build a little buffer for 50 ohms if needed but this thing doesn't have the input as far as I can see.

Whatever, more info Tuesday.
