My MESH Athlon 1800 PC has a CPU fan and it badly needs replacing.
It's a common 3-pin 12V, 60mm type. Its depth (which BTW never seems
to be included in specs) is about 12mm. That's considerably thinner
than 60mm case fans, and the screw holes are much smaller diameter
too.

After much googling I've so far still not found a replacement UK
source. Can anyone help please?

Neither my nerves nor skills are up to replacing the *heat sink*. I
want to replace only the fan.

Hello,

I would try Maplin if you have one nearby. Otherwise, I have also
bought from Midland Computers:

Thanks Kris. As mentioned up-thread, Maplin looked hopeful but a phone
call established they no longer stock any suitable 60mm types. But the
low-priced fan at
http://www.midlandcomputers.com/default.asp?area=prodview&prodid=1489
might be OK, perhaps with the plug adapter. The only minor snag might
be the larger hole diameter, but I imagine that springy washers would
ensure a snug fit with existing machine screws. (Don't want to have to
re-drill holes in the heatsink.)

Or glue spacers in the fan case holes to make up the difference. Then
again, if you've had this much trouble finding these fans locally, you
probably would have an even worse time finding various size spacers and
other misc hardware. <shrugh>
 
Sharp bought a bunch of Zenith picture tubes around that time. I have
seen the Zenith made shorting picture tubes in Sharp 25" sets do the
exact symptom you described. Possibly the 27" tube is shorting,
causing excessive current, and blowing the HOT.

Does anyone have a schematic of this (1976?) vintage integrated amp

Just Glue it in - if the surface is flat, then doublesided adhesive (mylar)
tape is good. Hotmelt or the "Silicone-rubber" glues will work well on
uneven surfaces. My harddisk is "taped" in.

One dab on each corner should do it. (By the time the replacement fan wears
out, the computer has been donated to a charity shop and written off in
tax).

certainly not the cause. Before changing the HOT I got a data sheet. I
replaced it with an exact same part with the same specifications.
However I don't think the HOT is the cause of the problem. I think that
the picture tube is shorting causing the blue raster, then putting a
load on the HOT causing it to fail. I've isolated the filament pins on
the tube circuit board and used Mr. Goldwasser's trick of having a
floating cathode circuit (wrap a wire around HV transfo ferrite). If the
short is to the cathode then the TV is fixed. Has been running now for
three days.

Disconnect the crt board and see if again it draws enough current to blow
another horiz output.then ring the LOPT.

Good point!

Have you ever noticed how MS bashers can usually remember every DOS command
and claim to still prefer it over a GUI, How ironic is that? Perhaps they
are just pissed because MS came up with a GUI that allows normal people to
use a computer?

And then there is the occasional MAC Guy who just feels left out and is
pissed at everybody. Ever noticed how these guys are usually left handed..

Before anyone gets pissed, is all in jest :)

BTW, Mr. Gates gives more money to charity each year than most of you will
earn in a lifetime... I suppose some of you will consider that to be tax
evasion....

I'm still not sure why my freaking clock runs slow...... lol....

Good day...

That's not true. He has already given away perhaps 6% of his total
lifetime worth. How many ordinary people have given away $100,000?

Matt, 10 yrs ago it used to remember the settings, 3 yrs ago when I
replaced the skinny dial lamps with white LED's I had the cover off and
could find no battery or memory cap. I suppose it could be flash memory
though I think it predates that. Thanks for the link.

What about % of income above the level to comfortably sustain an
individual/family? Someone earning $50k a year giving 6% is digging
deeper than someone earning $500k giving 6%, at least potentially.

if this had anything to do with Science hardware or electronics it would be
interesting. Suffice it to say that anyone who gives anything without
expecting something in return would be a great thing. However, charity, is
the furthest thing from most peoples minds, that give huge amounts of money
to anyone. Its all bout the business end of things.

Without question, someone giving away 6% of personal wealth that
they could not spend in 10 lifetimes is meaningless.

If I may inject some considerations. Money itself doesn't matter
except for a feeling of security. Richness doesn't necessarily mean
greedy. Possessions are a good indicator IMO. Also, time spent doing
something matters. Spending 6% of your time helping other people is
meaningful. Whether giving 6% of your income is charitable just
depends.

If I had as much money, I might never stop shopping and
get very little done.

How many people _have_ $1,666,666.67 to give away 6% _OF_? (which, BTW,
is probably a serious underestimate of Uncle Billy's "total lifetime
worth".)

If I have ten bucks in my pocket, and I give a street bum a buck,
am I more generous than Bill Gates, since that's 10% of my entire
wealth?

And another thing - there's a serious misunderstanding going around that
says that "size of pile of money" can in any way be related to "worth".

Just ask Nicklaus:

You are right. They get tax breaks for the big donations, but
someone who gives money or other gifts that can barely scrape by is
giving a lot more. When was the last time a billionaire given away every
cent they owned?

Its east to give away $100,000 when its just pocket change. I have
given away my last $5 to a friend who needed money to eat when I had no
job, and not enough food to feed myself the next day.

Somewhere in the Far East there is a big factory making shitloads of
crystals. These crystals have a nominal spec, but are subject to
tolerances.

Somewhere in that factory these crystals are measured. Those closest to
the designated frequency are shipped to Seiko, the farthest to Dell.

Watches tend to spend a lot of time strapped to a temperature-regulated
heat source (a human). PCs usually are not.

As mentioned in previous (non-technical) replies, PCs are not often used
as timepieces, so lower tolerance (cheaper) components will be used.

If you play with figures long enough, you can make Bill Gates look
stingy no matter how much money he gives away. But he is still giving
away billions of dollars, and he only has $50 billion to play with.

How much money does he have to give away before it meets your personal
definition of meaningful?

On whether you are hated as much as Bill Gates or not, apparently.
