Re: Pre-Owston Natter 26th Nov

And when it gets really cold, you can turn it on. Nah, that's when all the output transistors blow up. :shock: :lol: I used to have a humongous Perreaux 2150B 400W class A amp in my workshop that used to idle at about 60C. If it wasn't for the desk space and enormous electricity bills, it'd still b...

Re: driving licenses

What amazed me is that the 77 year old vicar with macular degeneration who ran full pelt into the back of my landrover has just had his eyes tested... ...and been passed fit to drive! By his own admission he has trouble handling transitions between light and dark. It can only be a good thing that yo...

Deffo take me off the list... Seeing grandchild this weekend is top of the list.

Terrible timing - be a while before I forgive our daughter...

Re: Op-amp operating voltages - a question

Never noticed any difference - the manufacturer's data also states that noise/performance is independent of supply voltage assuming that the supply is in range.

I've several detailed texts on op amps and their design - I'll have a look to see what the experts say...

Re: The Audio-Talk Motorcycling thread.

As you well know, the Boeing issue was a systematic failure - many many processes failed. If there is a positive from that, it's that the issues regarding changing flight control systems are now better understood and processes will be improved. Air travel along with rail, in terms of fatalities/km, ...

Re: The Audio-Talk Motorcycling thread.

Old story about pacemakers, which was rapidly addressed. Basically, when these systems were designed, security was not such a big issue. Either you are being deliberately obtuse and argumentative or simply don't understand safety critical and intrinsically safe systems. The amount of testing and ver...

Re: The Audio-Talk Motorcycling thread.

To quote from the post I was referring to that suggested flexible application of rules: It was they that suggested we open our own account. We had a limited company and enough land to qualify. Not that it's anyone else's business. Then (using that logic) I would argue that what I do with my motorcy...

Re: The Audio-Talk Motorcycling thread.

I don't trust any government, regardless of party. Her Majesty's Most Loyal Opposition are, IMHO, a bunch of ineffectual, lying weasels too. However, we are governed by consent in the UK. Unpopular laws rarely last long. God, I'm honestly shocked at this coming from you, Nick. It's only a short ste...

Re: The Audio-Talk Motorcycling thread.

Not sure we broke any rules. We legitimately purchased commercial glyphosate from a licensed agricultural merchant (where we had an account), and used it completely legally on an extremely invasive controlled plant.

Really not sure what your ad hominem beef is here.

Re: The Audio-Talk Motorcycling thread.

No, what was your point about our use of weedkiller?

Unless it was a pretty weak analogy. Comparing small companies doing upgrade work on vehicles to an invasive alien species is tenuous at best.
