It sounds like time to make some phone calls. Perhaps
someone still does television repair (I'd look for TV
repair in the yellow pages) and can work on HB's stereo.
That might wrap up the thread, at least on HB's part.
That's my vague, demented advice.

OK, wireless headphones: Sounds do-able. IMPORTANT: Would the sound I get through wireless headphones be the same as through TV speakers (blecch)? Remember the reason I had sound routed through stereo was TV speakers POS.
Or will headphones be better than TV speakers, and if so, why?

I don't see how if the speakers turn off when he plugs the headphones
in. But I've drawn stupid conclusions before. (Today I read something

even Black & Decker only charges 17 dollars for. Other places, $4, he
But you've just reminded me that there might be a resistor for each
channel in the headphone circuit, which he'll have to move or replace if
he replaces the jack. OP, don't destroy the resistor before you copy
the colors off it it and which color is at the end. But you can
probably reuuse the old ones.
I think we've all fixed things that weren't broken. The joy of doing a
good repair is mitigated by the fact that it was the wrong repair.

I've dealt with a similar issue that turned out to be a hairline crack on
the main board. Some stereos use switches to change from headphone to
speaker output, some use relays and some just use the jack's built-in shunt
I think there's a deeper issue here, and that is I don't see HB opening up
the unit and doing a jack transplant. No offense, HB, but electronics
repair doesn't seem to be your forte. Now it would be nice to know what's
under the hood in case you decided to get it repaired, but I'd still go with
other options like wireless headphones or a small dedicated headphone

might be equally tempted to buy a $25 headphone amplifier box with RCA
inputs and 1/4" stereo headphone outputs.

Remedial reading instruction, Higgy. Go get a lot of it. You'll
benefit more from some rudimentary education than you will from
kookdancing on Usenet, which you obviously aren't smart enough to
handle. Or you could just continue your kookdancing and kapslocking
and gurgle groping.
That's more than a little rude and I believe what irks you is largely the
fault of Google Groups. Although I've never cared one way or another about
who uses what to post, it seems Google's going out of their way to make
trouble for Usenet and people using standard newsreaders. AFAICT, they are
inserting control characters into the message stream that control indenting
via their own interface but can make replying via a plain text editor
extraordinarily difficult. I found I could not reply in-line to HB's
message without tabs appearing where I didn't want them.
If Google Groups are going to be *that* unfriendly and inflict a proprietary
framework on the NNTP protocol, then they should be shunned.
It happens to a lot of people venturing into unknown territory. It's part
of the learning process. I think you're being a little hard on the Beaver,
True, but it did communicate a sense of exasperation caused, in part, by the
way Google Groups mangles quoting. And by the fact that a lot of people
jump into the thread somewhere in the middle and don't read through all the
previous "asked and answered" information.
I was pretty sure she switched enough things around to eliminate most
potential problems. Eventually. And if she wasn't thorough enough in her
testing, guess who gets to pay for that inattention to detail? She does.
Sometimes that's a very good teacher. Just like there are people who have

I would guess that it means "The only problem was in the jack on the stereo"
(she's referring to her HK receiver as a "stereo" - pretty common usage).
How, exactly, does someone with no expertise in a subject differentiate good
advice from bad advice? She's probably much better off evaluating what's
been offered after having some time to digest it. I wouldn't go charging

As for opening the unit up and rebending the contacts, good luck with that.
If they weren't "springy" enough to resist deformation once, why would they
resist further deformation after being bent around some more? If that's the
problem it's bad design or material choice.
As Tony mentioned, pulling and replacing with a better quality jack is the
right answer. There's an incredible quality difference between a cheap jack
and a quality one. How would HB know that unless she's removed, soldered

No, any more than misspelling is the fault of a bad spell checker, or
bad penmanship is the fault of a leaky pen. Higgy Bozo chooses to post
utter crap. It's not like anyone is forced to use gurgle gropes. What
"irks" me, as you call it, is an idiot posting incoherent gibberish,
and blaming the idiot's own ignorance on Usenet.
Then why are you so intent on defending some cretin who insists on
posting gurgle grope gibberish?
And whose fault is it that Higgy chooses gurgle grope? Yours? Mine?
Poor baby. New around here?
OK, guess away!
In fact, early in the thread, I did. Read much?
So now you'll go off into a fantasy world, entirely of your own
invention, and pretend that somehow you're "translating" my posts.
You're not. Get a grip.
One thing's for sure, the jacks I reclaim from 20 and 30 year old equipment
are made of sterner stuff than the cheapo replacements you find on Ebay.
The sheet metal used for the contacts is thinner now, and more likely to
deform than jacks of old and the old build quality was just better, overall.
Solder eyelets, in particularly, are really much worse than they used to be.
Often stamped off-center and needing reaming because the hole was plated

There's never going to be an end to it - it's all part of the great bean
counter v. engineer design principle of "build it cheaper until we hear it's
started to fail in the field." Part of the problem of that theory is that a
company's reputation is also failing in the field at the same time. What
you save in making it cheaper can end up cheapening your company's name.
Compaq was one of the few that resisted cheaper engineering for a long
time - my 1980's SLT still runs my Ratshack PC "Metex" and SW flawlessly.
It gets cranky if I don't start it up every six months but that's the drive.
I want to retire it but it just keeps on working, decade after decade. The
display is pretty "Etch-a-Sketch" by today's standards, but I use it mostly
to capture meter readings over time to a *floppy disk* so it really doesn't
matter. The plastic has NOT gone brittle or turned green or brown.
Admittedly it's in what amounts to a retirement home for old PCs (my
electronics bench) but it's still an impressive record. In fact, even if
the HD dies, as it threatens to, I can still run the Metex meter SW from the
floppy with considerable room left for the data. You don't see code like
As for cost-cutting in general, I've used up a large number of small space
heaters since the '70s and nowhere is cost-cutting design more apparent than
in successive generations of that product. Every fraction of a renminbi

I think I have a dead HK upstairs I can check - no wait, it's a Sherwood.
My advice to HB is of course dependent on how she has the TV connected to
the HK. I assume it's line level audio out coming from jacks on the TV.
Most slim TV's I've seen acknowledge how crappy their built-in speakers and
provide one or more ways to "export" audio to a better reproduction device.
While most wireless headphones are equipped to "drop in" to a circuit made
with RCA patch cords, oddly, the only thing I have been able to find in the
wired department are four channel headphone amps. These take the signal via
RCA patch cables from a device's "AUDIO LINE OUT" jack and distribute it to
four separate headphone jacks with separate volume controls.
This one's $44 but a single channel unit should be out there for around $25.

If HB wants to learn, building a simple circuit is the way to go. If not,
maybe someone will voluteer to build it for her for cost.
I got my feet wet with the remarkable 555 chip, which wasn't very accurate
but certainly was very versatile (and CHEAP, too). First project was a
variable speed reversing relay control for my Uniroller film developer
complete with status LEDs (which sad to say were pretty new at the time) and
(completely superfluous) beeper.
As an aside, today I got an HDMI to composite device for $20 that solves the
problem of my new CCTV recorder having only VGA and HDMI outputs. Now I can
pump the CCTV output through the analog TVs throughout the house like the
old DVR did. I was pretty surprised when I went to connect the RCA "VIDEO
IN" cable of my home distribution network and there was no "VIDEO OUT" on
the new DVR as there was on the older one.
It was a reminder that like PC's, the connector that's been there for 20
years might disappear next year. <g> I didn't even think to check the specs
to see if the new unit had a composite video out. Now I get to find out if
the unit supports simultaneous video output to both HDMI and VGA. I have my
fingers crossed (but no M-M VGA cable so far to test with).
Some time ago a guy was setting up a headphone web page, by the name CMOY.
Was asking for designs for amps. He also has his version of an integrated
portable device. The site is Headwize or Headwise ? Lots of headphone
stuff. I sent many emails trying to get specifics on my amp. You can just
google szekeres amp.
It's simple, but I don't recommend it for beginners.

Asking everyone. Is this really true that one can damage the jack
pulling on the headphone cord? Maybe I'm consistently gentle, but I
can't imagine pulling on the headphone cord hard enough to bend anything
in the jack. The plug doesn't move enough (in any direction but in and
out) to bend anything.
I don't mind pulling on an electric cord to pull it out of the
receptacle. (No cord has ever suffered but if one did, it's easy enough
to replace the plug.) So I'm not that gentle.
Perhaps cheap materials lose their springiness?
And HB have you ever actually pulled on the headphone cord hard and at
I can't imagine bending what's inside the jack by bumping the plug
against something, even one's hand or fist. The parts inside the
jack, the tangs, are meant to bend as the plug is pushed in and the
wider part of the plug pushes them out of the way, so to be bent more
than that, they'd have to be pushed even more yet.
HB have you ever hit the plug when it's in the jack, accidentally it
would have to be, with your hand or fist, enough to bend something/

I've lost track of the details of this thrad, but I think this means
there is something wrong with both channels, somewhere. The likely
source of problems is alway the mechanical parts, in this case the plug
or the jack, or any mechanical volume control. Any volume or balance
control with a knob or a slider, as opposed to a push button to increase
volume and another to decrease.
But below it's clear that it's the jack, but it might be both channels
