Tell you what, I more than likely, was doing warranty repairs for
major manufactures while you were still in diapers

Suuure you were....

You don't need anything like 7kHz for clear speech. If you did, telephones
would be no use. AM radio in the UK is 4.5 kHz band limited.

Both of those have a lower bass response to match. This set has a very
uneven sound by comparison.


I mourn the day when usenet was abandoned by academics and taken over by
conceited amateurs.

Why are you posting then? A pro would have no problem in sorting out the
cause, you conceited little shit.

I'm posting to ask for advice.

I gave you advice. Then you in a very condescending tenor insult my
intelligence by advising me this was a /repair/ newsgroup.

I'm not pretending to be competent in this area and wasting other people's
time as a result, unlike some people.


Let's see you just posted this turd;

Seems you absolutely are pretending to be competent in this area by
judging others as /amateurs/.

Tell you what, I more than likely, was doing warranty repairs for
major manufactures while you were still in diapers so if you intended
to group me in with the conceited amateurs then you have a lot not
only to learn about electronics but also who knows what.

If you are looking for someone to guide you step by step on what to
check and possibly replace, at the very least provide a schematic of
the set.

Don't waste your time on him. He needs his glass belly button
polished so he can see what is going on. That also explains the
'muffled sound'.

I had to laugh at his concept of intercarrier buzz. I doubt he has a
clue as to what causes it, or what was done to correct it on TVs for 50
or more years.

Telephone spec is 300 - 3000 Hz.

But make up your mind. You were complaining about 'muffled' sound. Do you
understand the common meaning of this, sound wise?

Then you could keep your posts to the point.

You can't help with my question and are completely without clue, although
loathe to admit it.
All you've done is waste my time and, less importantly, yours.

Gee, you're a real charmer.

Well back in the 70's my best friend's father was selling and
repairing television. I repaired my first Quasar 'Works in a Drawer'
with him looking over my shoulder.

In the 80's I worked for a warranty repair facility and was
responsible for 19" < sets.

I think Jamie's original post was merely bait. To get noticed and then
to cry 'victim.'

EOS.

My family bought one of the first three Quasar 'Works in a Drawer'
sets that were delivered to the shop I worked while I was still in
school. It is sitting in my garage and still worked when I put it
there. It was upgraded to a Channel Master 25VAXP22 black matrix CRT
when the original 23EGP22 became too bad to watch.

In the 80's I worked for a warranty repair facility and was

I had moved on to broadcast engineering, and doing industrial
electronics, by then. Do you remember when the first character
generators hit the TV stations, and all the problems with intercarrier
buzz?

There is more and more of that crap on a lot of newsgroups.

I ended up with one a customer left at the store then left town after
it was repaired. I paid cost for the parts and had that set for
another 10 years.

Vaguely. But then I remember so many problems with specific chassis
that I repaired under warranty it kind of clouds the memory. Like GE
and their first VIR sets. Holy shit did I see a lot of those with
crappy soldered pass through eyelets. Can't remember the chassis
number range off the top of my head but anyone who did GE back in the
80s will remember them.

Fun sets to work on (for me) were the older RCA with SCR trace/retrace
flyback or sawtooth scan for HV. One in particular that I had to
replace the devices and tuning caps about once a year for almost
6 years until the old fella who owned it finally died himself.
Couldn't restart his SCR after his HV failed, heh. Sorry that was an
old shop joke.

Yeh but makes it easy to spot posers.

number range off the top of my head but anyone who did GE back in the
80s will remember them.

We didn't see a lot of newer GE sets. Zenith, RCA & Philco were the
three biggest sellers in the area.

Fun sets to work on (for me) were the older RCA with SCR trace/retrace
flyback or sawtooth scan for HV. One in particular that I had to
replace the devices and tuning caps about once a year for almost
6 years until the old fella who owned it finally died himself.

I saw a few of those, just before I left TV repair for good. I've
repaired exactly ONE TV since then, but I repaired so many monitors that
I've lost count. The intercarrier buzz was a problem, because most
techs would crank the AGC as high as they could, before overload. The
character generators pushed the video to the lower limit in the
baseband, and some went below that because of poor DC offset. That
caused the AGC to raise the gain a percent or two, causing a loud buzz,
or distortion. Of course, you couldn't convince the old timers, or
gypsies of the cause. We saw lots of sets that had been in other shops
for the problem. If it was carried in, we would just reset the level for
free and send them on their way with a warning to avoid shops that
didn't keep up with the factory training. We got a lot of shocked looks
and repeat business, when they needed real repairs.

Couldn't restart his SCR after his HV failed, heh. Sorry that was an
old shop joke.

Too bad 'Kill Filters' don't work like they should. Enough people
kill file an idiot on a group and they can no longer post to that
group. Get kill filed on enough groups, and you can't access any NNTP
server.
