Well OK it's Monday, sue me. I got a lawyer who can...nevermind. Back on topic...

So I put the thing back together and MF MF MF, no trace. Also the range lights, the ones that switch when you put a 10X probe on it, out. The vertical plates are about equal, the horizontal plate are not. One has like +65 volts and the other nothing. I don't know right now which is left and which is right but I would venture to guess it is not being triggered, even in auto. I am also pretty sure it is out of range, that plate should never hit zero DC.

I already looked back at everything I did, I DID leave off a little PF cap going to the shield on the attenuator body, but that can't cause this.

Well now it is a few hours later and I made my burn your balls spaghetti sauce. I mean if you like spicy you will be at my feet, so that is about 4 hours. It is not quite done, but it was still about 4 hours. I left it on.

I looked around for what feeds those range lights to no avail, it will take more 0aper pounding to find it I guess. But it should be simpler than that, like "Oh, I didn't plug that back in". That's why they taught us that when that happens go back to the last thing that was done before it stopped working.

I scrutinized my work and found nothing wrong. I looked all over the thing for plugs not plugged n shit. What else could've happened ? Blew something out ? The only way I could do that is by creating a short, and in the attenuator assembly there is no power whatsoever, so that would be one hell of a trick.

But now 4 hours later it has a trace and all is well with channel 2, but not response from channel 1, I just shut it off, we'll see if it comes on in a few minutes, and if it does, what does that tell us, and if it doesn't, what does THAT tell us ?

I saw the contacts drop to place the X100 in the circuit. It did not work. I pushed it with a diddle stick and it did. I bent it and now have all the ranges above 5mV or whatever, when the X100 kicks out. So now it is obvious that something happened to the switch that puts the X100 attenutator in and out the circuit.

So it is obvious I have to pull this thing a[part again, but I would like to be able to check its functions off. this is of course easier said than done. I'll have to take it apart again but the problem is to test it. I have no way of knowing how far that cam is, I guess I could measure the bumps on it but then how would I measure how far it is from the board with all the switches ?

I am more unhappy, the part I specially worked on is worse. I won';t give up but it is just, you know. To keep the edge I have to do it all over in a way, take it all apart and all that hist, and push the little thingies and have an ohmmeter on it. Would be nice to like five hands.

The way I see it, the absolutely worst case scenario is that the X100 module suffered an internal fault when I soldered it. And yes, I had to hit it multiple times. I had to, it just wasn't making the bond. What's more I got some solder out of the solder area, which brings us to another point.

This board is obviously copper, but is overplated with gold. As with any board it has connections to the components. Without solder mask the solder will cover all the foil, but it didn't. The only thing that makes sense is that they removed the solder mask after. And they have whose cutouts for connections to things with too much thermal mass, which would throw the whole process off.

Anyway it's like 6:00 AM and I had a couple beers and ate, I am getting tired. I will attack this tomorrow.
