So? There is a fine line where it is a matter of ego, instead of
repairing something.

Really? This comes up all the time on a one make classic car forum I read.
I'll open up things like switches and relays and clean them if they give
trouble. Most there seem to think it's better to buy new or used. And of
course 'new' parts that are 25 years old can have corrosion on the
contacts too. With a hobby, it doesn't matter much if it takes time to fix
something like that out of all proportion to the cost of replacement. It's
the satisfaction you get from doing it which is priceless.

The silliest, normally uneconomic, job I ever did was for someone with
cerebral palsey . (first time I came across that situation where you can
comprehend someone's speech only if you do not look at their face and get
miscued by distorted vestigial "lip-reading").
He drove (as far as i could tell with only the use of 2 fingers on a heavily
modified car) 15 miles and back , twice , for me to repair the motor of a
silly 12V fan that plugged into the car cigarette lighter. This fan kept his
pet dog/ gofor/ assistant happy sitting in the passenger side foot well. It
had a unique clip arrangement so any old fan would not do. Before the days
of mobile phones so he had a distinctive car horn beep sequence and I would
go out to him. It apparently took about 1/2 hour , with assistance from his
dog , to get in and out of the car.

Hello again all,

When I posted my request, I was trying to save a customer some money on
a repair that was getting expensive.

ONE person actually sent me an e-mail with some useful info on a web
site that had a similar cartridge at a reasonable price, and thanks to
him for that.

I had NO INTENTIONS of starting a thread on bashing an individual.

IF YOU CAN'T STAND POSTINGS FROM A CERTAIN INDIVIDUAL (including me)
DON'T COMPLAIN ABOUT IT. Instead, either skip over posts from that
person, or learn to use your browsers' features and block posts from
that person.

While I do find some people attempt repairs that I would not, I also
find that sometimes they have something useful to say, or have found an
reasonable way to repair something that I thought could not be repaired
for less than the cost of replacement.

Regards,
Tim Schwartz
Bristol Electronics

P.S. I had my brands wrong. The cartridges I used to see open windings
in all the time was Micro Acoustics, not Audio Technica. My apologies
to Audio Technica. (My memory is getting sort of foggy.)

Original post:

Hello all,

I've got a customer's turntable here with a Shure M105E p-mount
cartridge in it. The stylus is fine, but the cartridge itself has an
open winding. I've seen this in Audio Technica and Grado cartridges
over the years, but never before in a Shure. Any chance you've got a
good body without a stylus you'd part with? (In the USA preferred. I'll
gladly pay shipping.)

Thanks!

Great. When someone takes that effort to get things done the least one can
do is reciprocate.

About 20 years ago I made up a deaf aid for a favourite uncle. He did have
two very expensive pro deaf aids but didn't like them one bit. He was
house bound so only usually had one or two visitors at a time.

I made up a small battery amp with a compressor and peaked at around 2kHz.
Driving a set of ordinary walkman headphones. And a lapel mic on a long
lead. With that clipped on the visitor he could at long last carry on a
conversation easily.

I got the idea because he used headphones to listen to the TV and radio,
and said they were so much better than using his deaf aids with their
speakers.

Yes, really. Even in a hobby, some things waste too much time and
money. Those switches, for instance. If the insulators are cracked and
the contacts mostly burnt away your time would be better spent finding
one in better condition and refurbishing it.

That 25 year old NOS switch would be easier to refurbish, unless they
were all total crap when they were made. I have seen NOS thumbwheel
switches that had tuned to mush from the contact lubricant used by the
manufacturer. How would you fix that?

I've scrapped new PC boards that cost us $8,000 to build, after
finding internal shorts on the 16 layer circuit board. The board house
was paid to test every blank board before shipping them to us. They had
to pay for the scrap. There was no legitimate way to repair it, and
still meet our standards so it would never be shipped to a customer.

It's not your fault. There are a few megalomaniacs in this news group
that will jump at the chance to bash others. Example: Dave Nebenzahl
using your post to belittle N. Cook. No reason for it besides a childish
ego thing.

To the O.P.: as the one who took the thread off on a tangent, be assured
that I had no intentions of implicating YOU here. Don't worry; you are
blameless.

Careful, Meathead: after all, 'twas you who wrote in this thread:

Or are you now claiming that this was posted by an imposter?

There is a free version as well. Install it, run it then uninstall
it before returning the computer. I've had several new HP printer
installs go south. Revo fixed them. AdAware trashed during an update.
The built in uninstaller didn't work, but Revo did. The paid version
will do a complete scan of the registry to remove traces of everything
that has been removed from a computer, no matter when it was removed.

I've cleaned more registry files by hand than I care to think about.
Like removing VNC software and network drives that no longer exist. :(

I have also changed the displayed name of IE and other programs when
some know it all isn't looking. ;-)

Rather than answering your question directly, I'm going to ask you to think
about what sort of hardware would be required to do that. You can then
figure it out for yourself, and you'll have learned something in the
process.

What do IR signals have to do with RF amplifiers? Light vs Radio waves... I
don't see the connection. Please enlighten me to what you are trying to do.

I've got a friend's ASUS M5200 laptop that I've offered to look at.

It works fine when connected to it's power supply but dies instantly if the
power is removed. There are only ever two lights on on the front of the
laptop, one for the mains supply and one for the hard drive. The battery
light never comes on. The power meter in Windows does identify the battery
and shows it as having zero charge.

I've tried battery recalibration and a new battery has also been tried but
neither helps, it still refuses to charge. More in hope than in expectation
I've opened it up to have a look around but there's nothing obvious to see.

I'm guessing something has gone wrong with the internal charging circuitry.

Is there anything else I can do or have I come to the end of repair options
(short of motherboard replacement)?

Remove the battery and see if you can measure the voltage present at
the terminals the battery connects to while the charger PS is plugged
in. If you see no voltage there, it is a safe bet that the internal
components of the charging circuit are at fault. If there is voltage
there, you might consider the possibility of the terminals not making
proper contact with the battery.

The contacts all look undamaged and are soldered securely to the
motherboard. I'm not sure which contacts do the charging and what voltages
to expect so I've not done that (yet).

Repair, not recycle, but still a good idea.
