I actually lost interest in your crass and ridiculous rantings several posts
ago, but since you won't leave it alone, here is the bottom line. You are
not clever. You are not funny. Your wit is about as sharp as a kangaroo's
arse. Do you really not understand that the whole world reading this thread,
is laughing at you ? Lets be clear on this. That's laughing AT you, not
laughing WITH you ...

Your descent into the foul gutter language that always happens when anyone
sees fit to challenge you, merely shows you to be an ignorant fool, and
highlights your dubious heritage.

Now understand this. You can call me, and anyone else on here, anything you
like - I don't care. You don't offend me. I just pity your poor sad
existence. We have a saying over here. It goes " When the hole you're
digging gets so deep that you can't get out on your own - stop ".

And now I really don't have any further interest in you, or anything you
have to say.

And I don't mend televisions.

Phoul Arsehole?

No idea! (Wish I knew - I'd do it again! :-)

It really is time to ignore that **** - I suspect he's got a never-ending
supply of his own brand of phaecal verbosity!

Moving on to more serious/interesting* subjects - we're toying with the idea
of a steam train in the garden. I've Googled a bit and there's a ton of 'G
Class' stuff - can you cut me through to the nitty gritty and point me to a
good site where I can mug it all up and get prices? Amazingly, Swim (a Scot)
is keen on the idea and I was quite surprised to find most of the 'G Class
Societies' are up in Scotland!!

TIA

Ok, so who knows a bit about measuring audio power ? Setting aside any
furious arguments about peak power, rms power, average power, backpeddling
average peak music power on any given friday in March etc, does an audio
power meter sum the power in both half cycles to arrive at a reading, or
just one.

I guess what I'm asking is half wave reccy ahead of the meter, or full
wave
bridge ?

FWIW if its just the output of an audio amp I just use two bloody great
8 ohm resistors on a large heatsink with stout cables to reduce ohmic
losses, and connect that to the amp and use me trusty Fluke bench DMM to
measure the AC power developed when running a sine wave with the Hewlett
Packard distortion analyser keeping note of the distortion level to see
when its going into clip.

Measure that at a few different frequencies and square the AC measured
volts and divide by the 8 'ommes and thats the RMS power.

Sufficient and accurate and IMHO a good indication of what the amp will
develop.....

**Yep. Good enough for day-to-day stuff. I use the following:

http://uk.farnell.com/jsp/endecaSear...=9508180&N=401

A bunch of those nice, aluminium clad, 50 Watt resistors from Farnell.
They're bolted to a chunk of extruded aluminium rectangular tube. There's a
fan on one end and a thermal switch on the other. When it gets hot, the fan
switches on and cools the assembly (and warms the workshop, on these cold
Winter mornings). I have a bloody big old switch, so I can choose 8 Ohms, 4
Ohms or 2 Ohms for testing. Additional to that, but less often used, I have
a 0.1uF and a 2uF cap to switch across the load to test for stability. I
also use, less frequently, a dummy load, like this one:

http://stereophile.com/reference/60/

Mine has impedance minima to around 3 Ohms and there are other differences,
but this one is pretty good. As PA has indicated, such a test shows up many,
otherwise exemplary, amplifiers as being rather bad at operating into real
loudspeakers. All monitored by a 'scope and a wideband millivoltmeter. For a
long time I used a real power meter, using an analogue multiplier IC. It was
nice and convenient.

Hi Trevor

Yep, those are the exact same resistors as I am using, but in the 100 watt
flavour. Heatsink the size of the Titanic with a matching fan bolted to the
end, but mine runs all the time. Has proved very useful for repair of high
power PA amps, where the owner complains of things like " cuts out half way
through the second set ". I can now leave the amp thrashing away into this
load, with the scope hung on the socket I've provided.

** If all you want is to heat up a power amp and see when it shuts down -
no heat generating dummy load is needed.

An air cored, 5 mH inductor load driven at 200 Hz does the job FAST !.

Impedance = 6.3 ohms.

Phase angle = 90 degrees.

God I suppose...Ruperts god...

Nope, in those days Rupert Neve was a committed Christian and the rest
of the firm it appears had those leanings and that, in those days, was
the way it was there.

Of course these days they'd be done for discrimination of some sort or
another, or would have fallen foul of the PC brigade.

Course we're a bit more tolerant of more than the one religion these
days;)
