### WLM has a similar UI to OE - which is what I'm used to.
###I've also tried installing Xananews - the UI looks like it might be
tolerable but I get "pipeline out of sequence" error when I try to get
message body.
### Apparently "upgrading" to an older version of WLM can fix quoted text
indentation - but I've yet to find a copy.

What type or style of user interface do you prefer?
An example of a program that does it correctly will suffice.
My theory is that users tends to favor whatever they
learned first. Hopefully, you don't want something
that looks like a teletype machine output.
Did you at least look at Forte Agent?

Found a standalone install of WLM2009.

Just in case it helps anyone else, this is where I found the standalone
WLM2009 installer:
http://www.geekonthepc.com/2010/10/10/get-the-old-windows-live-essentials-2009-back/
There is a WLM2009 online installer on Filehippo, and the install files are
still accessible on the M$ server (for now!).
Live Essentials 2011 must be completely uninstalled first or it will report
there's a newer version installed and refuse to proceed.

Philips lamps used to have fuses built into the stem to prevent an
internal arc from blowing any external fuses. The problem was that they
cost a penny or two more, so none of the retailers in my area would
stock them.
Before buyig a bulb, it should be possible to see through the neck
whether it contains just plain wires or a pair of tubular glass fuses.

Do you buy cheapie "no-name" bulbs?
Try a Philips bulb -- at least for the US they make incandescent bulbs
with "dumet" wire inside the glass rod portion.

If it's unregulated it will have a higher output voltage.

What device is this adapter powering?

12V AC or DC?
Assuming DC, no problem if your unspecified device does not require
regulated power. Some power supplies have internal regulators. This
is very common with 5.0VDC adapters. Not so common with 12VDC
adapters, but still possible. If your adapter looks and feels like
it's just a big transformer, with just a diode inside, the replacement
is fine. However, if it looks like a switching power supply or the
unspecified device lacks an internal regulator, you'll eventually have
a problem with an unregulated adapter.
If AC, there's no such thing as a regulated AC wall wart so there
should be no problem substituting a high power adapter.
If DC, also, check the polarity on the DC power connector. Panasonic
phone devices and computah powered speakers sometimes use positive
grounds.
If DC, I usually don't have many failures with transformer operated AC
adapters. If they get hot, they may blow a thermal fuse, but that
takes real effort. However, switching regulators are another story.
For example:
<http://802.11junk.com/jeffl/pics/repair/slides/Motorola-2210-02-PS.html>
<http://802.11junk.com/jeffl/pics/repair/slides/2Wire-power-supply.html>
They're smaller, lighter, more efficient, cheaper, and turn off
without a load, but fail far more easily and more often.

Based on your question, the short answer is NO!
The longer answer is....
What is a machine?
sewing machine?
machine gun?
gumball machine?
Pinball machine?
Replacing an AC adapter with ANY DIFFERENT AC adapter
often works...except when it doesn't.
There are many subtle differences that CAN matter.
The fact that you asked the question suggests that you
don't understand those subtle differences.
Cheap devices are carefully designed to balance the
output of the supplied adapter against the needs of the device.
Are batteries being charged?
More expensive devices are often more robust, but I once
had a $2000 Compaq laptop computer that used the current
limit in the ac adapter to set the battery charge current.
BAD DESIGN, but there it was. Using a different adapter
was a disaster...ask me how I know.
Nobody can help you decide without more information.
Any advice you get based on your supplied info was made
by someone guessing.

You've tried all their canned food?
But you have no knowledge of their tools?
Others here have - including me. And I'd have no hesitation recommending
them as excellent value for money. But I don't have their generator.

All About The Quran
The Quran is a Divine Miracle of Literature [Prophesy - Science -
Warnings - Wisdom - Truths]...and it has been Preserved 100% In the
Original Language - for over 1,400 years!
Humanity has received Divine Guidance only through two channels:
The Word of Almighty God ("Allah" [in Arabic]) [scriptures, Bible,
Psalms, etc.]
The Prophets sent by the Allah to communicate His Will to mankind
These two things have always been going together, hand in hand.
More important though, there were at that time, tens of thousands of
his companions ("sahabi" in Arabic) who memorized the complete Quran
from the instruction of the prophet Muhammad (peace be upon him). Even
the prophet himself (peace be upon him) used to recite it with angel
Gabriel once a year and in the last year of his life he recited it two
times just before the month in which he died.
Next, the leader who came after the prophet Muhammad (peace be upon
him) (Abu Bakr) entrusted the collection of the Quran to be written in
one volume by one of the Prophet's scribe, Zaid Ibn Thabit. He kept it
till his death. Then the next leader, Umar and after him to his
daughter, Hafsa who had been one of the wives of Prophet Muhammad
(peace be upon him).
Then from the original text which now resides in Topkope Museum, in
Istanbul, Turkey, the next leader, Uthman prepared several other exact
duplications and sent them to various Muslim territories such as;
Uzbekistan and Turkey and other places. These scriptures are still in
museums there and one has found its way to a museum in England as
well. All of them are exactly the same. Today many of the Muslims from
these areas are still memorizing the Quran.
The Quran was so meticulously preserved because it is the Book of
Guidance for all of humanity for all times. That is why it does not
address just the Arabs, in whose language it was revealed. In fact
Arabs today do not comprise more than 13% of the Today of Muslims in
the world today.
The Quran speaks to "mankind"
Quran speaks to all of mankind on a general basis without regard to
race, tribe, color, social position, financial condition or genealogy.
Allah the Almighty says:
"O Mankind! What has seduced you from your Lord so Generous?"
[Noble Quran 82:6]
The Practical Teachings of the Quran
Teachings of Quran are established by the example of Muhammad (peace
be upon him) and the good Muslims throughout the ages have endeavored
to emulate his teachings both in thought and conduct.
The distinctive approach of the Quran is that its instructions are
aimed at the general welfare of the mankind and are based on the
possibilities within his reach.
The Quran is Wisdom Conclusive.
It neither condemns nor tortures the flesh nor does it neglect the
soul.
It does not humanize God, nor does it deify man.
Everything is carefully placed where it belongs in the total scheme
of creation.
Yet it obviously is not written in human style (chronological order).
Those who would claim that the prophet Muhammad (peace be upon him)
was the author of the Quran are claiming something that is humanly
impossible.
How could any person of the 7th century utter such scientific truths
as those found in the Quran?
Could he describe the evolution of the embryo inside the uterus so
accurately as we find it now recorded in modern science?
[See: Dr. Keith Moore's book - on embryology]
Secondly, is it logical to believe that Muhammad (peace be upon him)
who up to the age of forty was marked only for his honesty and
integrity, began all of a sudden the authorship of a book matchless in
literary merit and the equivalent of which the whole legion of the
Arab poets and orators of the highest caliber could not produce?
And lastly, is it justified to say that Muhammad (peace be upon him)
who was known as "Al-Ameen" (trustworthy) in his society and who is
still admired by the non-Muslim scholars for his honesty, would lie
about receiving the Quran (which forbids lying) from the Angel Gabriel
and then still be able to establish the best human society on the face
of the earth, based on truth?
Surely, any sincere and unbiased searcher of truth must come to the
conclusion that the Quran is the revealed Book of Almighty Allah.
Readers can easily see how the modern world is coming closer to
reality regarding the truth of the Quran.
We appeal to all open minded scholars to study the Quran in the light
of the aforementioned points.
We invite all to challenge the validity and accuracy of the sciences
known to man today and keep in mind that this is the EXACT TEXT used
by the Prophet Muhammad (peace be upon him) over one thousand four
hundred years ago.
We are sure that any such attempt will convince the reader that the
Quran could never have been written by any human being ever.

The RCA number is 272062 which I have seen listed using similar numbers to what you list. I believe that the suffixes are more for manufacturing locations than differences in the supplies. You should be fine making the substitution.

### WLM has a similar UI to OE - which is what I'm used to.
###I've also tried installing Xananews - the UI looks like it might be
tolerable but I get "pipeline out of sequence" error when I try to get
message body.
### Apparently "upgrading" to an older version of WLM can fix quoted text
indentation - but I've yet to find a copy.

What type or style of user interface do you prefer?
An example of a program that does it correctly will suffice.
My theory is that users tends to favor whatever they
learned first. Hopefully, you don't want something
that looks like a teletype machine output.
Did you at least look at Forte Agent?

Just in case it helps anyone else, this is where I found the standalone
WLM2009 installer:
http://www.geekonthepc.com/2010/10/10/get-the-old-windows-live-essentials-2009-back/
There is a WLM2009 online installer on Filehippo, and the install files are
still accessible on the M$ server (for now!).
Live Essentials 2011 must be completely uninstalled first or it will report
there's a newer version installed and refuse to proceed.

Philips lamps used to have fuses built into the stem to prevent an
internal arc from blowing any external fuses. The problem was that they
cost a penny or two more, so none of the retailers in my area would
stock them.
Before buyig a bulb, it should be possible to see through the neck
whether it contains just plain wires or a pair of tubular glass fuses.

Do you buy cheapie "no-name" bulbs?
Try a Philips bulb -- at least for the US they make incandescent bulbs
with "dumet" wire inside the glass rod portion.

If it's unregulated it will have a higher output voltage.

12V AC or DC?
Assuming DC, no problem if your unspecified device does not require
regulated power. Some power supplies have internal regulators. This
is very common with 5.0VDC adapters. Not so common with 12VDC
adapters, but still possible. If your adapter looks and feels like
it's just a big transformer, with just a diode inside, the replacement
is fine. However, if it looks like a switching power supply or the
unspecified device lacks an internal regulator, you'll eventually have
a problem with an unregulated adapter.
If AC, there's no such thing as a regulated AC wall wart so there
should be no problem substituting a high power adapter.
If DC, also, check the polarity on the DC power connector. Panasonic
phone devices and computah powered speakers sometimes use positive
grounds.
If DC, I usually don't have many failures with transformer operated AC
adapters. If they get hot, they may blow a thermal fuse, but that
takes real effort. However, switching regulators are another story.
For example:
<http://802.11junk.com/jeffl/pics/repair/slides/Motorola-2210-02-PS.html>
<http://802.11junk.com/jeffl/pics/repair/slides/2Wire-power-supply.html>
They're smaller, lighter, more efficient, cheaper, and turn off
without a load, but fail far more easily and more often.

Based on your question, the short answer is NO!
The longer answer is....
What is a machine?
sewing machine?
machine gun?
gumball machine?
Pinball machine?
Replacing an AC adapter with ANY DIFFERENT AC adapter
often works...except when it doesn't.
There are many subtle differences that CAN matter.
The fact that you asked the question suggests that you
don't understand those subtle differences.
Cheap devices are carefully designed to balance the
output of the supplied adapter against the needs of the device.
Are batteries being charged?
More expensive devices are often more robust, but I once
had a $2000 Compaq laptop computer that used the current
limit in the ac adapter to set the battery charge current.
BAD DESIGN, but there it was. Using a different adapter
was a disaster...ask me how I know.
Nobody can help you decide without more information.
Any advice you get based on your supplied info was made
by someone guessing.

some wallwarts use a positive ground DC plug,others use the usual negative
ground.

You've tried all their canned food?
But you have no knowledge of their tools?
Others here have - including me. And I'd have no hesitation recommending
them as excellent value for money. But I don't have their generator.

All About The Quran
The Quran is a Divine Miracle of Literature [Prophesy - Science -
Warnings - Wisdom - Truths]...and it has been Preserved 100% In the
Original Language - for over 1,400 years!
Humanity has received Divine Guidance only through two channels:
The Word of Almighty God ("Allah" [in Arabic]) [scriptures, Bible,
Psalms, etc.]
The Prophets sent by the Allah to communicate His Will to mankind
These two things have always been going together, hand in hand.
More important though, there were at that time, tens of thousands of
his companions ("sahabi" in Arabic) who memorized the complete Quran
from the instruction of the prophet Muhammad (peace be upon him). Even
the prophet himself (peace be upon him) used to recite it with angel
Gabriel once a year and in the last year of his life he recited it two
times just before the month in which he died.
Next, the leader who came after the prophet Muhammad (peace be upon
him) (Abu Bakr) entrusted the collection of the Quran to be written in
one volume by one of the Prophet's scribe, Zaid Ibn Thabit. He kept it
till his death. Then the next leader, Umar and after him to his
daughter, Hafsa who had been one of the wives of Prophet Muhammad
(peace be upon him).
Then from the original text which now resides in Topkope Museum, in
Istanbul, Turkey, the next leader, Uthman prepared several other exact
duplications and sent them to various Muslim territories such as;
Uzbekistan and Turkey and other places. These scriptures are still in
museums there and one has found its way to a museum in England as
well. All of them are exactly the same. Today many of the Muslims from
these areas are still memorizing the Quran.
The Quran was so meticulously preserved because it is the Book of
Guidance for all of humanity for all times. That is why it does not
address just the Arabs, in whose language it was revealed. In fact
Arabs today do not comprise more than 13% of the Today of Muslims in
the world today.
The Quran speaks to "mankind"
Quran speaks to all of mankind on a general basis without regard to
race, tribe, color, social position, financial condition or genealogy.
Allah the Almighty says:
"O Mankind! What has seduced you from your Lord so Generous?"
[Noble Quran 82:6]
The Practical Teachings of the Quran
Teachings of Quran are established by the example of Muhammad (peace
be upon him) and the good Muslims throughout the ages have endeavored
to emulate his teachings both in thought and conduct.
The distinctive approach of the Quran is that its instructions are
aimed at the general welfare of the mankind and are based on the
possibilities within his reach.
The Quran is Wisdom Conclusive.
It neither condemns nor tortures the flesh nor does it neglect the
soul.
It does not humanize God, nor does it deify man.
Everything is carefully placed where it belongs in the total scheme
of creation.
Yet it obviously is not written in human style (chronological order).
Those who would claim that the prophet Muhammad (peace be upon him)
was the author of the Quran are claiming something that is humanly
impossible.
How could any person of the 7th century utter such scientific truths
as those found in the Quran?
Could he describe the evolution of the embryo inside the uterus so
accurately as we find it now recorded in modern science?
[See: Dr. Keith Moore's book - on embryology]
Secondly, is it logical to believe that Muhammad (peace be upon him)
who up to the age of forty was marked only for his honesty and
integrity, began all of a sudden the authorship of a book matchless in
literary merit and the equivalent of which the whole legion of the
Arab poets and orators of the highest caliber could not produce?
And lastly, is it justified to say that Muhammad (peace be upon him)
who was known as "Al-Ameen" (trustworthy) in his society and who is
still admired by the non-Muslim scholars for his honesty, would lie
about receiving the Quran (which forbids lying) from the Angel Gabriel
and then still be able to establish the best human society on the face
of the earth, based on truth?
Surely, any sincere and unbiased searcher of truth must come to the
conclusion that the Quran is the revealed Book of Almighty Allah.
Readers can easily see how the modern world is coming closer to
reality regarding the truth of the Quran.
We appeal to all open minded scholars to study the Quran in the light
of the aforementioned points.
We invite all to challenge the validity and accuracy of the sciences
known to man today and keep in mind that this is the EXACT TEXT used
by the Prophet Muhammad (peace be upon him) over one thousand four
hundred years ago.
We are sure that any such attempt will convince the reader that the
Quran could never have been written by any human being ever.

The RCA number is 272062 which I have seen listed using similar numbers to what you list. I believe that the suffixes are more for manufacturing locations than differences in the supplies. You should be fine making the substitution.
