From: "William Sommerwerck"

I first learned about the "warranty of implied merchantability" and related
common-law consumer protections over 30 years ago in an article in -- of all
magazines -- "High Fidelity". I still have a copy of it.

It's nice to see that others are aware of the protections that dealers and
manufacturers wish to disown.

But what does "fully functional" mean? I'd be surprised if it meant
"containing every function the consumer desires." I would expect it to
mean something along the lines of "containing full functionality of
every function it's described as containing, or that one would
reasonably expect it to contain."

Version 1.0 certainly should have been fully functional, and anyone who
bought one without notice of its flaws is clearly protected by the
legislation. But I can see nothing to stop a vendor from deleting
functionality from the specification before selling a product. The
product is then fully functional, according to its specification. At
most the vendor must ensure that the customer is on notice of the change
to the specification before the sale is concluded.

We have implied warranties of merchantability in Australia too. Indeed,
they're now common in many jurisdictions, and it's not possible for the
supplier to contract out of liability under the warranty. But if I'm a
car dealer, and I have a new car to sell that has been scratched, all I
need do is ensure that the contract of sale states that what is being
sold is a scratched car, and the consumer has no grounds for complaint.

Thanks for the real-world feedback, Fred - it's good to hear.

A bit of Googling on the subject of "WD-40 sticky" suggests that the
problem with stickiness developing, seems to involve use of too-large
amounts of WD-40 in situations where the lubricated device is exposed
to significant amounts of dust and dirt in use (e.g. pocket knives,
hand tools, etc). The residual oil (the nonvolatile part of WD-40) is
apparently rather viscous, and can be prone to pick up dust/dirt and
form a sticky sludge under these conditions.

In a mostly-sealed potentiometer, inside a mostly-sealed electronic
cabinet, this probably would not be an issue.

How About a Clean Break – with Israel?

By Philip Giraldi — MP3

Back in 1996, a group of leading neoconservatives led by Richard Perle
drafted a memorandum for then (as now) Israeli Prime Minister Benjamin
Netanyahu, recommending that Israel adopt a more aggressive and
assertive policy towards its neighbors. They called it a "Clean Break"
to suggest that it would be a major shift in policy. Today, as American
foreign policy looks more like a shipwreck than a victory lap, there is
perhaps a need for a Clean Break by Washington. As the relationship with
Tel Aviv has an impact far beyond Israel's size and importance it
should, ironically, be the first element in the foreign policy disaster
that is examined.

Many Americans who indulge in the mainstream media believe that Israel
is a close friend and ally to the United States and that when it is
criticized the complaints are often unfair and might even in some cases
be motivated by anti-Semitism. Some Americans, mostly evangelical
Christians, actually believe that Israel is a special nation either
because it is the homeland of the Jewish people or anointed by God and
that all other nations of the world should defer to it and protect it.
Still other Americans realize that Israel is a nation with good and bad
aspects but are intent on using American power and wealth to nurture it
because they share either ethnic or religious ties with it.

Some Americans look beyond the bumper sticker definitions to recognize
that Israel is indeed like many other countries in most respects but
that it is also a special nation in that it has as its protector the
most powerful and wealthiest nation on earth. Some think that role to be
appropriate because the US has an obligation to guarantee Israeli
security, while others would disagree. Those who disagree frequently do
so because they find the Israeli influence over the United States to be
a dark force, sometimes leading Washington and its elected officials to
endorse policies that do not serve the interests of the American people.
They would cite examples like the Iraq War, in which supporters of
Israel played an enabling role, as well as the ongoing agitation to
attack Iran, which would be a replay of Iraq only much much worse.

That Israel is able to control many aspects of America's relationship
with foreign nations is clear and the hubristic Israel Lobby makes
virtually no effort to hide what it is doing. On January 18th, Senator
Kirsten Gillibrand of the Senate Foreign Relations Committee wrote a
letter to Secretary of State Hillary Clinton calling on the United
States to veto any resolution in the United Nations condemning the
Israeli settlements policy. The settlements are illegal under
international law and the pending resolution in the UN carefully uses
the precise language previously employed by US administrations to
criticize their expansion in an attempt to create an acceptable document
and avoid a veto, but the result is not good enough for Gillibrand.
Joined by 15 other senators as cosignatories, Gillibrand maintains
fatuously and falsely that any criticism of the settlements "hurts the
prospects for a peace agreement and is not in the interest of the United
States." In reality, as she well knows, it is US acquiescence in the
settlements that damages the US standing in the world.

The past ten days has also provided several other examples of how Israel
exerts a strongly negative influence on American foreign policy.
President Barack Obama's State of the Union address urged support for
democratic forces in Tunisia. But he did not provide similar support for
the democratic forces in Egypt and for the new government in Lebanon,
which are both nations currently experiencing political unrest. Why?
Because both are frontline states with Israel, meaning that Washington
can only consider its relationship to them in terms of whether their
political developments are good for Israel or not. This has been
excruciatingly clear in the numerous comments by US government spokesmen
relating to developments in Cairo: Israel is almost invariably
mentioned. The United States prefers to give Cairo billions in aid and
covertly support the dictatorial rule of Egyptian President Hosni
Mubarak because Egypt has kept the peace with Israel. Washington will
likewise oppose any government in Lebanon that is beholden to Hezbollah,
even if it does not threaten the US or American interests in any way,
because Hezbollah is the enemy of Israel.

Looking at the Middle East region objectively, one has to question
Washington's actions. The US national interest is to have a peaceful
resolution of the Israel-Palestine conflict, which would require an end
to the Israeli settlement policy. It also mandates non-hostile relations
with Lebanon and Egypt, nothing more. The Suez Canal is the only asset
controlled by Egypt that has international significance and it is in
Cairo's interest, no matter what kind of government it has, to keep it
open and bringing in revenue. Egypt, Palestine, and Lebanon produce
nothing that the US needs to have and they are not important markets for
American goods. None of them threatens any genuine American vital interest.

In another related development, last Wednesday newly elected senator
Rand Paul said that he favors ending all foreign aid, including the aid
given to Israel and Egypt, because the United States can no longer
afford it. Rather than encouraging anyone to debate the issue on its
merits, the Israel Lobby, Democratic politicians, and a representative
from Paul's own Republican Party immediately attacked him, saying the
proposal was unthinkable. Well, think again. Israel gets billions of
dollars yearly from the US for no good reason beyond its ability to
manipulate Congress and the media. Paul's opening the door to a serious
discussion about ending that subsidy is long overdue.

Senator Gillibrand's excursion into fantasy, Rand Paul's experience in
opening Pandora's box, and the developing situation in Egypt together
illustrate how Israel is a United States national security liability and
always has been. The relationship narrows the options that US
policymakers can pursue in dealing with problems relating to the Muslim
world. Arguments that Israeli and American foreign policies are and need
to be identical based on shared opposition to international terrorism
and other such "values" are fallacious and are based on constructs that
are essentially false.

Israel's bad relationship with its Muslim neighbors has led to frequent
wars and more limited military actions since the founding of the
country. In a normal world, the onus would be on Israel to establish a
modus vivendi with its neighbors, but it has regularly chosen to use the
mailed fist as its first option. Since it is a small country lacking in
resources, it has only been able to accomplish this by seeking out what
might be described as a force multiplier. To that end it has opted to
use its powerful lobby to shift US policy in its favor, relying on
America as a source of funds and both political and military protection.
Its leading politicians have even bragged about how the United States
does its bidding. This has done extreme damage to the United States,
which has initiated at least one war as a result, and has been engaged
in what must be described as a nearly continuous and escalating conflict
with the entire Muslim world on behalf of Israel. This has trashed
America's reputation and has come at a real cost of trillions of dollars
and thousands of lives. The benefit to the American people has been zero.

In accomplishing its strategic objective of making the United States its
permanent protector, Israel and its lobby have also corrupted both
Congress and the White House and have created a permanent distortion in
how Washington sees the world and responds to it. Israel's enemies, even
if they do not threaten the United States in any way, have become
America's enemies. This has made the US in the eyes of much of the world
the enabler of Israeli actions and has in turn made Americans the
targets of international terrorism. Osama bin Laden was very clear on
the subject, stating that the United States is a partner in the Israeli
oppression of the Palestinians. The Israel relationship is a recruiting
tool for those who seek to do harm to the United States. Without the
Israeli nexus, there would have been no 9/11 and there would be no
hysteria about the danger from terrorists driving growth in government
and the development of the anti-libertarian security state.

And the relationship is expensive. Israel seeks to militarily dominate
its neighbors. It does so with American-provided weapons and maintains
its edge through US coproduction agreements that essentially fund jobs
in Israeli defense industries that compete directly with US companies
that sell the same products. Even though Israel is one of the richest
countries in the world, Washington gives it a vast array of advanced
weaponry for free and also hands to it the technologies that enable it
to eliminate American jobs. As Israeli companies can bid on defense
contracts just as if they were American companies, they frequently also
wind up getting the work that would go to Americans. Because of the high
level of American direct aid plus unique tax breaks for American
citizens who give money to Israel, Israelis have free medical care and
university education, benefits that few Americans enjoy.

And, finally, Israel is not afraid to bite the hand that feeds it. It is
annually rated by the FBI as the "friendly" country that is most
aggressive in spying to obtain US defense secrets and advanced
technology. The mainstream media is complicit in not featuring stories
that relate to Israeli espionage, but the cases number in the hundreds.
Several spies who have been caught in the act have received a slap on
the wrist instead of real punishment. One, Ben-Ami Kadish, was even able
to continue to receive his government pension after stealing and passing
on defense secrets.

Now I will be the first to admit that my narrative presented above
reveals my own biases in that I am appalled at what Israel and its
supporters have done to my country. But I have to believe that by any
objective standard, the relationship with Israel does nothing good for
the United States and does, instead, a great deal of damage. That
leading policymakers are afraid to challenge the billions of dollars
flowing to Tel Aviv while US senators line up to sign on to a letter
that opposes their own country's interests is a tragedy of epic
proportions. That Washington will define its own interests in the Middle
East largely in terms of whether they are compatible with those of
Israel is nothing short of betrayal of the Constitution, which
established a national government that would benefit the American people
and make them both safe and prosperous. One hesitates to borrow rhetoric
from the neoconservatives, but sometimes even they get something right.
It is indeed time for a clean break, but this time with Israel.

I'm reminded of an old Rodriguez cartoon in Popular Electronics.

First panel: On a large speaker cabinet. "to prevent shock do not
remove cover"

Second panel: Owner taking out a LOT of screws.

Third panel: Owner on floor clutching chest. Inside of huge cabinet
has 2" transistor radio speaker inside.

They are only a tamperproof head of which there are various and easily
available.. Wait until you come across a coffin head screw.I believe the
reason for using them is that some countries prevent the dismantle of an
appliance without the use of a tool or special tool so this way all fields
are covered in one assembly. Did you find out how it worked. They are made
to break. Best way to keep them longer is to keep the Blades clean and
lubricate the bearings NOT with WD40 or the like.

As I said, it hadn't broken. I was actually trying to figure out which
wire was which leading to the induction motor. I had in mind making it
run backwards. Aerofoils don't perform as well backwards, but they do
perform. However, on further consideration I realised that the fan
blades would be aerodynamically stalled if the fan ran backwards, with
the result that it would probably not work much at all.

ok i will ask him about his insurance...i was hoping that he could at
least turn it on and get an LED error code
thanks for the advice.
cheers,

If the transistor was being used for bias compensation, then yes. Most
likely one per channel. In the case of voltage regulator transistors, the
rails are shared between both amps in most common hifi units, so only one
transistor required per regulated rail, no matter how many channels are in
there.

By some accounts the original bakelite was up to half asbestos (which kind?
WHite or blue?). I saw online some electrical outlets made of bakelite, and I
was wondering if it really is bakelite, and if so if there is a new bakelite
without asbestos? ANy clues?

From an electronics engineer within an exempted industry, noy just allowed
to use leaded solder but contractually must use tradional materials in there
entirety. His company does not automatically believe documentation that
comes with components specified as being non-RoHS. They test whether the
tinning is 100 percent tin or traditional and not rely on
fraudulent/erroneous paperwork. The implication is that other exempted
end-users would not be so stringent

Owner has seen this thread
http://community.whathifi.com/forums/t/313192.aspx
and would rather I looked at it rather than the maker

Easy to blame PbF as printed all over as such.
Problem is different to that above thread. For ages now the R ch has failed
occassionally at switch on. Switch off and most of the time it comes up.
Very rarely that ch dies in use, Then last week both ch failed at sw on , so
he decided something needed doing

Anyone know how to find mechanical data on 16 amp output relays
Make Finder 40.615 , clear cased so can see the contact gaps
About .75mm for the R one and .5mm or so for the L. Thinking fine contact
contamination and not enough mechanical punch-through.
Both relays in series from one supply and TA3717 ptotector IC
Or any other ideas other than checking phones socket, if wired in to affect
output somehow, PbF solder looks fine. Wanging with engraver and nylon bolt
has only highlighted a microphonic capacitor.

Looks like another amp where I'll make an LED mod that the owner can view
through the phones socket. Bring out pcb mounted, relays-on LED ,and add a
different colour one for the main rails supplies on, both viewable through
the phones socket transparent plastic panel at its rear

Finder Relays search on www.findernet.com just gives me a useless run around
