Also, temerature is an issue. Mostly people sell things by only one number,
being it Mhz for PC's, watts for (l)amps and irons and number of ways for
speakers, but there's often more to life.

So for Irons, it's also temperature (some 280 degrees celsius) you can
alter temp by replacing the bit! tons of bit are available. Also bitsize
matters for obvious reasons, and flexiblity of the wire. Due to stupid fire
regulations, I can only buy stiff wired  irons, causing the iron to jump of
my table and alarm me with the funny smell of burning carpet. (yes, black
holes)

I'd say, you want to do it qiuckly, before you're components start smelling
odd.

First, get rid of all cats first. This makes your life easier to handle.
So, change cables. Sound? repair your cables.
Still no sound?

Open the desk is probably nasty, but repairing will be easy.
The connectors have probably been ripped of a bit from the print.
Look carefully for broken contacts at the green noncomponents side of the
print, and resolder them.
Then pick your largest screwdriver, poke around near those black
multilegged parts, and close the desk again.

>Now, did you know that three-phase is a Swedish invention?
It's what comes from a generator! You'll have three coils rotating in 1
magnetic fields, thus providing three phases with steady distances.

Pinwise or location wise?
Pinwise depends on the configuration, star or around...
