I thought I'd go through all the capacitors from the 4503 that I recapped and it was just as I suspected at the start when I wasn't convinced that doing a full recap is not always necessary, but most of us here do it any way, not a single capacitor actually warranted being replaced, all had very good ESR and capacity wise, were well within the spec by a good margin, so that was my first full recap and may well be my last without testing some of the caps at random. 

Yebbut there's always the chance of damaging the board.

I currently ought to replace these, to remove spurs that are -70dBc down:


And I have to replace those Rifas for the obvious reason:



Fear is giving me the opportunity to improve my techniques and tools

It looks like just a routine cap change to me. I would get rid of all of them, including that little yellow tant. Considering the total cost of the capacitors and the time/labor avoided later in troubleshooting it's cheap and a no brainer.

Cost is not the problem; PCB damage is the downside. And I'll ignore that I can't easily find a source of some replacement caps due to height restrictions and the lead pitch.

The nasties, compared to what I've done before are:

• four layer, large buried groundplane
• small tracks
• small pads
• why do the thin axial caps have three leads
• difficult access to the caps
• penalty of screwing up: a nice hp8562b spectrum analyser bites the dust

I'd argue that once Japan got their corrosion problems under control, they proceeded to make some of the most reliable cars in existence. Which Ford never, ever, have managed, starting with the Taunus and Granada, where the order of the day is fill up on engine oil and check the fuel   

We have a saying here, that goes:
'Mit dem Ford fort, mit dem Zug zurueck!'
 

Fix Or Repair Daily

At least it’s not a Fiat. I’m not going there again.

Y'all just don't know any better. You paid for a Chevy Nova and got a Yugo; how wouldja know any better when all you've ever driven is a Opel?

Do you know, by the way, that Ford car manufacture in Europe exists solely to make Opel the second worst car being made?

Basically correct. Although, when I think 'yuck! - Opel' I have to remind myself that I drove one once. Got an Vectra 4x4 as a gapfiller and got so used to it that I kept it for over a year.

I had a 72 Opel GT as a teen... was a lot of fun, but I spent more time fixing rusted sections that broke as I drove than I did driving it. Unloaded it after fixing a spring perch in the back that broke through the trunk.

Nein! I may be old and I may be a grandpa but I ain't no fuddy duddy. 

In fact, if I were in Germany one of these would be in my driveway....



And I'd be doing this....

[AVGresponding]

I wouldn't touch any VAG with an extended barge-pole.

The amusing acronyms for car manufacturers are something of a stereotype.

I've had Fords and Vauxhalls that have been excellent cars in terms of reliability.

The fact remains, the first Vectra I saw irl, was on fire, at the side of the road...

FIAT = Fix It Again Tomorrow


Those Nippon Chemicon caps are probably better than the ones you're gonna put in as replacements...

Ok, this may be not as old as yours but it is a nice offer, for a Porsche 911 (and it is black!):

But driving on the Autobahn here in Germany ... I think, you have to do this now and at night. Otherwise there is way too much traffic on the roads. And I recommend to visit before a safety car training, because you Americans aren't used to this kind of speed usually.

My first HP midget power supply is here. Not yet checked out, but was sold as functional.
It will replace a similar one from Power Trade, which I have pledged to the budding lab of a friend.

Not going to be on Discord today. Rough night last night trying to sleep and now it is catching up to me. I'd probably start snoring with the mic on. 

So I'll catch everyone next week.

On the bright side I believe it’s easier to find  the 8477A than the 11683 range calibrator!

Cool. I'll have to check out the manual to see what it takes to calibrate the calibrator. TEA!

I had to rebuild my 190VDC reference. For some reason the original LR8N3-G regulator decided to give up the ghost. I might have accidentally shorted it. Anyway, new regulator and it's back up.

It's not the greatest reference in that the regulator is spec'ed to 5% so it does bounce around. But it's suitable for spot checks.

You DO love your 8505A, don't you?     

I take it to bed with me every night. 

Whoa....too much information thank you, what you get upto with your 8505A is up to you

I think before I can partake in such a session, I need a new computer.

But another thing: the cable finder (called 'Finder plus') from 3M shown below: is that a inductive wire tracer like the probes from Ideal etc., or does it need a specific generator to work with? Anyone knows the thing?
