He appears to be confusing sublimation and evaporation with boiling.

It is *correct*, as you've all been very hasty to demonstrate.
It is not so precise as to say "at 0.010C", but certainly that
value is well within the normal meaning of "0C" (what, -.5 to
+.5 C!).

The pressure is commonly known, was not the point, and your
question was out of place and trivially ignored.

Which is to say, who cares if you asked a dumb question?

And while sublimation might happen at that temperature too, as
might just simple evaporation, the fact that it doesn't break
into a full nucleate boiling state does *not* make what was

Huh? The issue is not whether water can be a gas at 0C, rather can it
*boil*. Since there is nowhere in the phase diagram that the water and
gas phase touch each other at 0C, my guess is that it cannot boil at
0C, at *any* pressure. It's only a guess though. ;-)

What a lot of you are missing though is that the diagrams you are looking at
are equilibrium states. Take a large quantitiy of liquid water at 0.05 C
and let it stand. Now, have it in a chamber at something like 1 kPa. Next,
*rapidly* reduce the pressure on the surface (maybe suddenly open it to a
large vacumn chamber). You can then get evaporation to cool the liquid and
at the same time get some of the water to violently change phase to a gas
(i.e. 'boil'). You will also get a far amount of ice formation as the
latent heat of vaporization is supplied by fusing some of the water into
ice.

Of course, this is only a transitory phenomenon, but it is 'boiling'

There are literally hundreds of references on the web about DC, AC and

that's what it's all about. The math determines the signal type. It

No, it sounds to me like he knows his phase diagrams. Water can indeed
be made to both boil and freeze (simultaneously) near 0C if the
pressure is appropriately low. I don't recall the exact pressure, but
it's a medium vacuum (1 Torr, 50 Microns,... ???) That combination of
temperature and pressure is called the triple point of water because
all 3 phases of water exist in equilibrium there. It is a fundamental
property of water that can be used to calibrate thermometers.

The best advice I can give you is to stay focused and fix the "Left Channel"
problem.... then you can evaluate the overall performance and make a
decision about a "shotgun" repair involving ALL of the caps.....
personally, if the amp is working fine after your specific repair, I
wouldn't fix it.....

My NAD 3125 may need new caps (it is 20 years old). All original caps
look fine, and are ELNA brand, either RE or CE series. I cannot find
ELNA online, although I may check a local store. I've been told
Panasonic FC series are good. Are they a suitable replacement for the
originals? They are "low impedance" - is this the important criteria
for audio? ELNA appears to be well respected in the audio world from a
bit of searching I've done, so I don't want to lose any of the
original NAD sound by using the wrong caps.

The one problem my amp has (see earlier post) seems to be isolated to
the left channel infrasonic filter section. Assuming I can resolve this
be replacing the caps in that section, should I just quit there?

Many people have said to just replace all caps on a 20 year old amp,
but the Panasonic spec sheets show that 20-30 years is a reasonable
lifespan for caps at near room temps. The 1000-2000 hrs ratings seem to
be at the max operating temps. Replacing all the caps seems like a
fair bit of trouble, especially if the result is a possible loss of
sound quality if the new caps are inferior to the originals, in terms
of audio quality. Any insight is appreciated!

I have a magnovox model #RJ5540-AK01 that only picks up snow and no
sound on all channels. The cable connection is good (from a sattelite).
Set initially had only black raster, but now has decent brightness
since tapping on CRT neck board. The rear A/V jacks give a perfect
picture and sound. I suspect a bad tuner, but how can I determine if
the tuner is bad, and is there another suspect compenent I can check. I
am a beginner and have only been working televisions for about 1 year.
Thanks group for any suggestions.

I don't have any experience with your particular set, but here are
some general tips.

Meter the tuner's pins. It appears that your tuner is getting power
(B), otherwise you wouldn't see snow, just a white or black screen.
Check that the band switching pins (BU, BH, BL) respond to band
changes (UHF, VHF high, VHF low). Also check that the tuning voltage
(VT) increases and decreases smoothly as the channels are scanned.

A bin job, basically.
So, now to either get an ultra cheap crapo TV, or a TFT which I will

Don't get any cheapo set unless you wan to to go shopping again in 16
months time.

Here we go with the crap advice again! Go and look up The Sale Of Goods Act
(visiting RETRA's website would be a good idea as well) and you'll soon see
why any TV should last considerably longer than sixteen months, and the
legal remedies you have should it not do so.

Here in Australia we also have legal remedies which we can exercise
for trivial cost with the ACCC (consumer affairs). Even though the
manufacturer/distributor may only offer a 1yr warranty on a TV, there
is an implied expectation of merchantability far in excess of that.

I agree brand doesn't matter. I use Xicon brand from either Parts
Express or Mouser. Mouser's prices and selection of caps is better.
The big caps are probably OK. I'd replace those in the amp and power
supply. You better believe 30 year old caps are bad, or will be
soon! If you replace capacitors, it's only the electrolytic caps
that you need to replace.
