Seems like it should be the easiest thing in the world, but I'm ashamed
to admit I'm having trouble with this.
 
The replacement headphone plug has three gold-plated terminals, and the
headphone lead has three enamel-coated wires coming out: if the plug is
oriented in the 12 o'clock position I have red to right, green to left,
gold to the center pin.
 
I sand down the wires, tin them, and then do my best to solder them up,
but the holes in the terminals are very small and I don't see as well
these days.
 
Unfortunately even when I think I've got all three wires making a solid
electrical connection to the terminals, I'm often getting only one
channel, or intermittent contact, or wires shorting against each other
somehow.
 
Any suggestions to improve my game here?

Buy a large illuminated bench magnifier (since you have already come to
terms with eyesight). Also use a handy-andy bench clamp (or pair of
them) to get everything aligned before heating the iron...

BTW, I don't mean to chastise you unduly, as you did try to help
scientifically.
 
It's just that telling me the obvious stuff about gasoline isn't helpful
since we all know the obvious stuff.
 
Of course, if mixing gasoline with, say, naphtha causes it to become
unstable or explosive or something like that which is NOT OBVIOUS, then by
all means warn me.
 
But to warn me that a chain saw can cut off my finger, or that I can fall
off a ladder or winding a garage door spring is dangerous or that running
while holding sharp scissors can hurt someone, is just wasting everyone's
time stating the obvious to people who know it already.
 
So, I'm ok with 'real' warnings. Just not useless California nanny warnings.
Make sense?

>I use gasoline as a home goo-gone substitute for removing labels.
 
If the base material can tolerate some heat, use a hot air heat gun:
"How to Remove Stickers and Labels Using Heat"
<http://www.todayshomeowner.com/video/how-to-remove-stickers-and-labels-using-heat/>
 
I don't know what kind of labels you're using, but the ones that I
have to remove from customers laptops uses easy to remove rubber
cement type glue, that is easily dissolved with almost any hydrocarbon
solvent. The trick is to let the solvent soak into the paper label or
soften the edge of a metal label. I think I use paint thinner.
 
However, I sometimes run into old labels where the glue has hardened
to something like a rock. For those, I mechanically scrape off most
of the label with a plastic razor blade paint scraper, and then attack
with the solvent.
<https://www.amazon.com/Plastic-Double-Edged-Razor-Scraper/dp/B004623NU2>
 
Well, you could try using something that was actually formulated for
removing labels:
3M General Purpose Adhesive Cleaner, Quart, 08984
<https://www.amazon.com/gp/product/B00ZIM9XPI>
Ouch. Rather expensive at $25/quart.
SDS shows interesting and noxious chemicals:

Toluene 108-88-3 0.5 - 1.5 Trade Secret *
Benzene 71-43-2 < 0.1 Trade Secret *
For naphtha, use Coleman camp fuel. Xylene and toluene are no longer
available in California, so those won't work.
 
There are made for purpose label removers, all of which really smell
awful. Goop-Off, Un-Du, Turtle Wax T-529, Goo-Gone, etc.
 
Then, there are the home concoctions:

The only thing I know of that will "dilute" gasoline and make it
less flammable is Carbon Tet - which has serious safety issues itself
and has been illegal for years.

But "real men" are not "totally" stupid. They mitigate danger where
it makes sense - and in your case it does. I hope you haven't fathered
any kids yet - the world doesn't need any more Bannons with yout
cheap-assed attitude. Buy a commercial goo remover that is safe
(relatively) to use - and use it outside in fresh air - because they
ALL STINK.

The non-abrasive/non-orange waterless hand cleaners will make alkanes
emulsify and wash away with water. Instead of gasoline, just use a few drops
of odorless paint thinner, applied with an eyedropper.
 
Then rub some goop on it and wash off.

Naptha won't help the flammabilty/explosive danger. Butane is even
worse. Methanol is corrosive, VERY flammable and poisonous (absorbs
through the skin too)
 
Dichloromethane may be an alternative but it has serious health risks
as well

My favorite 'nanny' warning from childhood was on a package of sodium
hypochlorite pool conditioner: 'Do not mix with brake fluid'.
 
Who would ever get the idea to make such a mixture otherwise?
 
PS: Make sure you are outside if you want to try this. It would also be a
good idea to put on safety goggles as well. And be patient. When the smoke
starts, don't attempt to speed things up by adding more of anything.

If you live near the border, go to Tijuana, go to a liquor store and buy
agua diente, It is pure (180 proof) ethanol. Fifty years ago it was $0.50
per liter, going to be more now.

+ He does not know that I am a retired chemist. I survived many fires
and explosions and release of toxic materials in the lab so I sorta know
what I am talking about. Then from the technical side, if the gasoline
is diluted the polar characteristics will change and it may not function
the same.

I will reiterate my recommendation, use WD-40 for label removal. If the odor is too offensive for your manly
sensibilities, buy the product in liquid form. If you do not atomize it with a spray, the odor is far less
pervasive.
 
With WD-40, apply a light layer to the label and just let it sit for a little while. Come back in 10 - 15
minutes and the adhesive will have dissolved and the label will slide off with virtually no work.
 
If you need a powerful solvent that will dissolve almost anything else, buy a can of lacquer thinner (yes, it
is available in California) LT is unbelievable in it's utility.
 
Use of and storage of gasoline and other highly carcinogenic chemicals mixtures inside the living area of a
residence is as inadvisable as smoking or leaving a loaded, unlocked firearm where might be accessible by a 5
year old child.

One time, not thinking what I was doing, I poured a little hardware
store acetone into a Styrofoam cup, and instantly ended up with a big
gloppy mess of acetone and melted Styrofoam on my lap.
 
Then I felt dumb.

Tangentially related: if you ever discover to your horror that you have
some white deodorant residue on a black dress shirt, Armor All interior
detailer spray gets it right off.
 
Don't ask how I came to know this.

Dedicated label remover is better than WD-40 and the orange smell is
quite nice.

Naptha, AKA lighter fluid (Ronson brand) or paint thinner). Or "white
gas" AKA camping gas (coleman gas, or the stuff they sell at REI by the
quart).

The heaters in Klystons used a lot of power, that had to be removed as
heat, in a water chiller. One 25 KW UHF transmitter that I rebuilt used
a pair of 1.5V, 1000A heaters per tube. That was 3 KW, then the fan on
the water chiller was a 480V, three phase, 5 hp motor. The circulating
pump was anther two HP. None of this ended up at the output port.

That doesn't answer my question of whether
or not AT transmitters use less power than
NT. Just a simple Yes or No would suffice.

3 Studies SHOW Why Coconut Oil Kills Waist Fat.

The meaning of this is that you actually burn fat by consuming Coconut Fats (including coconut milk, coconut cream and coconut oil).

These 3 researches from big medical journals are sure to turn the traditional nutrition world around!
