London is fine. I’m in and out of the city 2-3 times a week. Safer than any Essex town on a Saturday night. You tend to find that any issues are between isolated groups of people.

Well not necessarily. The original ones were technology constrained. We have a lot better materials now and a lot bette electrolytes. As long as you stay off the cheap ones then you’re fine. I’ve got a rule of Vishay, Epcos, Rubycon, Panasonic only.

The X100 attenuator comprising of C60 and C61 has cold solder joints. I was able to pull the assembly off the board with little effort. Now normally this wouldn't be a big deal. Put it back on and re-solder. But not this board. You can't get to the backside of the vertical board unless you pull it. And it's going to be a nightmare to pull. I'm thinking of cutting my losses and just using it as a single trace scope.
Bd139, what do you think? You have a lot of experience with 465's. Pull it or leave it? Right now I'm going to get some sleep. Had to work some overtime tonight and then come home and discover this shitty issue. :rant: :wtf:

I’d pull the vertical out and re-solder it if you can. While you’re at it clean the leaf switches on the back of the board too. It’s not too difficult to get out. Just watch that little carbon comp resistor connecting the attenuator to the front end. They break in half. I’ve not had a say joint on one of them yet. I’ve usually seen smoked attenuator modules though. It’s always the 100x one that gets toasted.

Personally I'd say pull it, but that said I have no idea just how difficult that is on Teks having never owned one. The finished result should be worth the effort though, bd139 always makes his look so dammed attractive.

In Essex for starters, we don't have a history of terrorism so that aspect alone must make it safer, one less threat and far far less organised crime gangs fighting over turf.

Terrorism is minor compared to other crimes.
Also I think you need to read up on the drug dealers in Essex. I used to go out with one :)

Crime is everywhere, but so far we don't have moped gangs etc, shootings are very rare etc.
SWMBO works in Crown Court so I'm only to aware of what happens around here, and according to what the media reports and I hear locally, there is no doubt about it London is the crime capital.
I wonder what RS will do now with the 3478A now that they have seen the photos complete with the exifs that prove when they were taken. There is no way that a momentary short via the solder would render it unrepairable, it was not even powered up for gods sake. The cynic in me thinks that sales of new meters might be down and they are trying to get me to buy one, no frigging way am I buying one. [emoji16]
