A Sony' CRTs color is screwed up.

Many moons ago, I came up with a simple demonstration
that showed clearly how a number of different make and
model stereo power amplifiers sounded exactly the same.
"Sounded exactly the same" is not the same as "were indistinguishable under

With respect to context, you stated that the purpose of the test was to
convince audiophiles that their belief that every amplifier had a distinct
sonic signature was invalid.

Perhaps, but Bob Carver proved the opposite.
I don't know whether he "proved" it, but he claimed that the principal sonic
difference among amplifiers was variation in frequency response into a
reactive load. By fiddling with the amplifier's response, he could reduce or
eliminate the audible differences.

Larry Archibald rented a motel room for Bob, and challenged him to make one of
his solid-state amplifiers sound like an Audio Research tube amp. I don't
remember the results.

You are, of course, correct. Let me offer an apology to William and
to this newsgroup for having provided at least half of the noise and
argumentation here. The personal attacks certainly do not add to the
body of technical understanding, and no doubt add confusion and
anxiety needlessly.
I will accept this in the spirit in which it seems to be offered.

But... I expect you to make an effort to understand the need to respect other
people's time, and think at length before subjecting them to a barrage of
objections -- especially those that fall into the "I don't believe what you're
saying because it doesn't fit my preconceptions" category.

YES, I have been where you are. More than 40 years ago, my network analysis
teacher -- who was the finest instructor in anything I've ever had -- jumped
down my throat for asking what he considered a stupid and lazy question. That
exchange continuous to influence -- some might say poison -- the way I
interact with people in UseNet.
 
Some Sony Trinitron portable sets were "live chassis" jobs.
Almost all the circuitry is at main voltage -- so you need an
isolation tranny to work on them.
And not just portables. I once damaged a KV-1920 because I "assumed" a set
with a switch-mode supply necessarily had an isolated chassis.

Perhaps, but Bob Carver proved the opposite.
My recollection is that Carver nulled the difference signal between some highly regarded amps and his own prototype, doing so in order to "voice" his to imitate theirs. By using (again as I recall) passive reactances, he was able to get the two transfer functions so similar that their null was down many tens of dBs.

The outcome of all of this was that no audibly discernible differences could be reliably reported, at least according to Carver in his claims.

This method obviously did not account for the different dynamic characteristics of the two amps, such as output transformer saturations and harmonic spectra / distortion changes over the dynamic range of the amps.

A clever technique technically and brilliant marketing IMHO.

Ironically, I spend some amount of time with my grand-kids preaching

this very topic arose tonight at a birthday celebration, where my 5 year

Never apologise to a troll - it only encourages them.

In retrospect, so very obviously true in this case, and my mistake for
acting as a gentleman and following my natural instincts to be

I have wasted too much time already with his nonsense.

I need to apologize for speaking the truth? For calling you on the line for

You insult people, then respond with a "Who, me?" and a cutesy "apology". Who

a desert.

Shall I quote Whitman?

"Have you learned the lessons only of those who admired you, and were tender

those who braced themselves against you, and disputed passage with you?"

You just don't get it, do you?

Nicely done. I'm surprised that you didn't hear any pops and clicks
as the input capacitors charged and discharged when hit with random
points on the audio input waveform.

Once upon a time, I worked part time for Federated Electronics in Smog
Angeles selling hi-fi equipment. I was paid on a commission basis, so
selling certain items were preferred. At the top of the high
commision list were big custom speakers. Near the bottom were the
numerous commodity amplifiers and integrated receiver/amplifier boxes.
I took one of the big speakers and attached a very low end AM/FM
portable radio to the speaker. A few hundred milliwatts was
sufficient for demonstrations. It actually sounded quite good.
Customers would inevitably ask "What's playing". I would then pull
the little radio out from behind the speaker. After the initial
shock, I preceded to lecture on the importance of proper speakers and
how they should purchase speakers first. If there was insufficient
money left, the need buy only a tolerable amplifier and radio. I made
quite a bit of money on selling high commission speakers, until they
changed the commission structure to slow me down. Grrrr...

The store also had an amplifier and speaker demonstration switch
board. It was a real switchboard, with heavy cables, and big
electrical panel type connectors. To discourage customers from
tinkering, nothing was labeled. My hearing is far from perfect, but I
could not tell the difference between any of the better amplifiers.
There were huge differences between speakers, but not the amps. Even
after hours, when I could turn up the system full blast to check for
high level oddities, I couldn't hear any differences. I did find some
really cheap amplifiers that failed in various ways, but once above
the low end junk price level, amps were much the same.

TBH, I took it as a rare flash of comedy from Phil. I thought it was
just 'tongue in cheek'?

The only interesting "flash" from Phil would be spontaneous combustion.

You are much too forgiving of Phil's grotesque misbehavior,
simply because he is extremely knowledgeable about electronics
and electronics servicing.

It is he who created the problem with his beyond-rude behavior. Neither
I nor anyone in this group is obliged to tolerate it or remain silent.

But in this case, I really think that it was just his way of expressing
tongue in cheek humour. Perhaps it doesn't translate into American?
British and Australian humour are very similar.

** Of course it was intended as humour.

Of course it wasn't. You are emotionally disturbed person who says
whatever he likes because he knows he can get away with it.

I see the same thing in every UseNet group. Person A attacks person B, and
when B defends himself, he's jumped on as the cause of the problem. Human
beings are moral idiots. They tolerate bad behavior, then blame the
victim.

Phil is clearly /capable/ of doing serious harm to someone (though whether
he actually would is unknowable). When it happens, everyone in this group
will say "Oh, gee, I never suspected. He was just making jokes." Yeah,
sure.

Phil is not a lighthearted clown. He has emotional problems. And if you
can't see that, if you think the rude, nasty things he says are "just in
fun"... What can I say?
I really am having some problems with understanding this. As you very well
know, me and Phil have had our spats on here, some very vitriolic. Yes, he
can be an odd person and just 'go off on one' sometimes. Obviously, on those
occasions, the things that he posts are certainly not "in fun", and I'm sure
that he would be the last one to pretend otherwise. But hey-ho, that's life
in the rough and tumble of usenet. For all his inter-personal faults, I
still respect the depth of knowledge that he has on a variety of subjects
under the 'electronics' banner. That has nothing to do with forgiving or
otherwise. It's just a fact. I obviously know that you have had some equally
bad exchanges with Phil over the years, but feel that you can't move on from
them, and that's fine.

But where I am having the 'real' problem here, is why you are calling him
out on the "Tears" response that he made to the comments I posted regarding
his technical ability. I know that subtle humour often doesn't translate
well into American, but this was quite clearly an "Oh shucks!" tongue in
cheek humourous response. Try as I might, I can't detect any malice in it. I
really think that you are seeing this from the wrong angle ...

And implying that I am too dumb to able to tell the difference ...

Well, what can *I* say ?

As to purity errors being visible on black and white pictures, other than
the fact that the the phosphors have different efficiencies, and the
drive levels are different for assorted reasons, it doesn't actually
matter that much that the phosphors are being excited by the 'wrong'
beams. The mix will still make something that approximates to white - or
shades of grey - sufficiently well for it not to be glaringly obvious.
More a sort of 'dirty patch' on the picture. However, as soon as a colour
picture is viewed on the same gaussed up CRT, the error is immediately
visible


** I am still using a CRT monitor for my PC.

When I hold a speaker magnet about 6 inches away, white areas of the
screen become mottled with grey shadows.
Yes, exactly. The 'dirty patch' that I described, which is grey rather than
white, because of the slight differences in drive levels and phosphor
efficiencies

However, the coloured parts change colour, blue to red, red to green etc.

Which of course, is immediately visible, because predominantly, only one or
two phosphors are being excited, rather than all three, which is the case
for white through grey.

QED.

** FFS stop wasting your and our time.

Is the set's de-gaussing thermistor working or not ??

Don't know yet. No time or space to take it apart. Have to make
room.

Does it go * BONG * at switch on or NOT ??

No, I made a special effort to listen. Turned it on several times.
I hear a relay click, but the sound is almost the same turning it off
and turning it on.

But I don't think this tv ever went BONG, like one other did.

Odds-on it is the problem and when fixed the set will de-gauss itself.

That's added incentive to turn it around and take the back off.


** Be very careful poking about on the PCB !!!!!

Almost all the circuitry is at main voltage - so you need an isolation
tranny to work on them.


.... Phil
Agreed. If you can locate the degaussing posistor, just remove it from the
board, and shake it. Usually, a faulty one will rattle. One of the two
thermistors in it will crack or break, and then it falls to bits. This often
results in the spring tension holding the other one in place, to be
released, so that one falls loose into the case as well. They are usually
roughly the size and shape of a highlighter (pen) cap - the stubby oval
type - and can be black, white or blue, and normally have three legs.

Go to Google images and type "posistor" into the search field, if you are
not familiar with what they look like. There are loads of images of them on
there.

** Bob Carver only ever made transistor amps - notably under the Phase
Linear and Carver brands. It is generally only tube amps that have such high
output impedances that speaker loading affects the response audibly.

Where an audible difference REALLY exists, there will be an easily measured
difference too. This what Bob found and figured he could emulate with a few
passives added to one of his designs.

It is not necessary to match amps so precisely to make them sound
indistinguishable in normal listening circumstances.
