The good thing about British cars is that the fuel economy is terrible on paper, but usually ends up being really good. Very little tyre wear too.

Easy question: what is the wavy semi-horizontal line by the red part, and why is that liquid illegal under international Protocols?

true about the fuel economy. I have been driving the car at about 11.5 l/100km.

Not bad for that gizmo with its 416 hp ...

Fuel economy metrics are some of the most stupid metrics. What really matters is the fuel used.

After all, it is easy for someone travel between two places in London to manage >50mpg (even in normal times). All they have to do is go via Manchester at a steady 56mph

used for long distance, normally cruising at 130 - 150 km/h with short sprints to 230 - 250 ...

I take it you're referring to the manufacturer figures? As far as I'm concerned the total miles driven divided by the total fuel used is the fuel economy.

There's a place reserved for him you in the -2nd circle of hell

I assume Equipnet turned out to be morons then?

They told me, very explicitly and repeatedly, that you could win all items in a bid packet, or none, but not some. Guess what happened.

Still, looking at the P6015 fleabay prices, I'm not worried

I suspect they lost by their own rules

I always wondered about using transformer oils in those instead of Freon.
Wonder if there's now synthetic oils capable of sufficient insulation that wouldn't muck with signal fidelity. 

[bd139]

I've seen people run PCs in synthetic oil. You'd expect that would have similar levels of buggery to signal integrity on the bus and they seem quite happy.

I was not talking about exotic cars, just about normal everyday family cars. To me a city car is small, easy to park, small engined but capable of the 20-30MPH speed limits and thus economical and normally carrying just 1 occupant. Family car capable of carrying up to 4 average sized people and capable of meeting the national speed limits while still being reasonably  economical and an exotic car is something that is capable of far more in terms of sheer speed, performance but can be a single seater or more and would normally be used for sheer pleasure or a statement piece.

I certainly would not want to drive a city car on a trip from say London to Bristol but I'd gladly do that in a family car. You may have other views however I suspect that not many would would use a city car for journeys which involved speed limits of 40mph and higher.

Have you driven any of the modern city cars? They've become surprisingly mature cars. Long distance driving tends to be somewhat more comfortable in a larger car of equivalent age, but the difference isn't nearly as profound as it used to be. When I add in the additional fuel and maintenance costs I'm not sure which I prefer. The city car is definitely more fun.

While I could not for a single moment believe that driving a smart car would be anywhere as near the comfortable experience you get from driving say a Golf and certainly not my car which I can get into the high 40+mpg from it, I can concede that they have matured a bit. That said I seriously doubt however that would be any good for me as I'm 1.9m tall.

All this is to create a saturated FREON atmosphere that allows the probe to go to full 40kV instead of ca. 12kV when filled with air.
FREON is also a much better conductor of heat and this is needed to cool the divider resistor at very high voltages.
Problem: FREON is *banned* under ROHS laws, IMHO. You can still get it officially, but only 1) you're authorized 2) you fill in a ton of paperwork 3) pay a boutique prize 4) proove that it will not evade to the environment.
Plan B: Try to find an old refrigerator. Some of the old gas fills could be usable.

Think mine is classified as a city car (Citroen c3). Absolutely great long distance. Also only 1.0L and runs on gnats farts. I haven’t put any petrol in it since February now  . Think in the 2 years I’ve had it, it’s cost me £520 inc full service. My fathers Range Rover that he had would eat 3x that every service.

Nope, the city car from Citroen is called the C1 and now there is the all new Ami (electric city car with a range of just 40miles) 

[Specmaster]

my city car is a small Ford, a 2003 Expedition ...

When "fuel economy" means buying enough fuel to keep the economy afloat. 

That ford is more like a Range Rover.

On the Rossman front, to be brutally fair to the guy, his beef is not just not Apple, it is the whole right to repair across the whole spectrum of goods, regardless of the makers name / brand. As he rightly states, years ago no matter what you brought in the electrical / electronic arena, it almost certainly came with a schematic printed and attached inside or on the back of the equipment or even the owners manual / instruction book.

Yes I have seen some dodgy repairs that he has done BUT what we don't actually know, is what does he tell his customers about the repair, he may for all we know, tell them that it is nothing other then a temporary fix and recommend that they purchase a replacement soon before it goes again.

Having watched a lot of his repairs, he does go to lengths to explain to the viewer why he does what he does normally, and he says that he would rather fit a replacement part if only Apple would make that part available, such as a motherboard when tracks have been destroyed by corrosion etc, so he is not quite the cowboy that he is portrayed to be.

In all honesty, I have done many of the types of bodges that he has performed on damaged tracks  by soldering reinforcing wires along the tracks pathway on multiple tracks to repair PCB's in gear that have suffered breaks due to being dropped or other rough handling and those items are still going strong today, many years ago I patched them up. 

[bd139]

Yeah the issue is that I’m sure your repairs weren’t done on or near GHz differential signal paths in hardware without ECC RAM....

It might look like it works in Rossman’s repair but signal integrity is data integrity and if that’s gone then what’s the point.

He should hold that stuff dear as I do with my three GOOD fire extinguishers.

"F gases" appear to be banned in new products. Apart from ROHS, there is the Montreal protocol.

The P6015A uses silicone.

Personally I wouldn't trust an old fridge's gas to keep me safe!

[Specmaster]

In that assumption you would be correct, but equally I'm sure that he understands just where that would be critical, but for the most part, those repairs are in the main to provide a connection to a chip where liquid damage has eroded the pad that the chip needs to connect to and I'm pretty sure that those would not be a critical path. I have seen plenty of these critical paths on The Signal Path channel and these critical paths are normally easy to spot and not normally chip to chip short traces.
