--- Quote from: med6753 on May 20, 2018, 08:51:07 am ---Well I found out what's wrong with Channel 2 on the Tek 465 and it's not pretty. 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:

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.

It doesn't matter what any of us think; you and I both know that now that you know what the problem is, you're not going to be able to live with the 'scope (or yourself) until you either fix it properly or ship it off to some other poor bastard. Until you do it will just sit there mocking you; every moment of the day and night.  :-DD

You got that right. I hate doing something half assed. Leaving this 465 with one dead channel is definitely in that category. Now that I've slept on it I've decided come hell or high water I'm gonna fix it.

I pried the top off X100 attenuator and checked it under a magnifier. I don't see any burning or other damage. Between the 2 inner pins I measured 1.0MEG. From the inner pins to all the outer pins I measured open except one which was 10K. I assume this is OK since the schematic does not show it's inner detail. The "opens" should be the variable caps. I cleaned it in IPA. I'll gently scuff up the pins for good solder adhesion.

Don't have time today to start pulling out the vertical board. I'll definitely report back.

"I come from Essex,
In case you couldn't tell.
My given name is Richard,
And I'm doing ... very well."

--- End quote ---
Couldn't agree more, I feel much safer in Essex then I would / do in London area for instance. I have worked all over the London area for the last 35 plus years and never once felt at risk, however that is not the case these days for a whole host of reasons.

I'm afraid it's the same situation though, it's the minority who spoil it for the majority. Because of the authorities inability to deal with those people effectively, I don't see things getting better anytime soon. [emoji850]

Ah, you've missed it. Perhaps you're not of quite the right generation (although for some reason we all seem to be remarkably close in age). That's Ian Dury's spoken intro to the song "Billericay Dickie".

Aside from it being a showcase of high-technology precision manufacturing, we see people... lots of them  (and interestingly, a large percentage of them women  ;)), gainfully employed, doing work that requires skill and patience. Fueling a good work ethic, and fueling the economy.

This is the precise opposite of the bean counters' goal; which is to reduce all jobs to monkey work so that skill has no value therefore demands as little pay as possible, and then if possible, to replace those monkeys with machines that require no paycheck at all.

Well you can only hope that Trumpy can get some of that manufacturing back as it's now mostly done in Asia even by the big brands and whatdoya know..... and by lots of women too.

As requested by some of the members, here is a small selection of photos from the Shuttleworth evening air show Saturday 19/5/18










And these ones were taken at North Weald Airfield when I went to watch the Gnat Display team training for the upcoming display season and was also escorted by a member of the airfield ops team to the opposite end of the airfield which is off limits to the general public, to get some photos of some Jet Provosts coming in to land and also do a few running breaks. There was a lot of general aviation landing and taking off as well and I include just one of these planes landing. Taken on 20/5/18












All of these photos are totally unedited and are therefore straight from the camera.

Nice photos as always  :-+
