You would not live long in a TV shop Rod, because
you *dont* know the proper safety procedures
concerning the handling of Cathode Ray Tubes.
You've never had a fucking clue, child.

( unless you enjoy being hit, or the trash man hit by 35,000 volts )

Just unpluging the set does not discharge it !
Never said it did. It is safe enough tho if you want to wreck it.

Wrong.

Usually does, but that's no reason not
to discharge it manually to make sure.
Not really worth the trouble, it wont kill you even if it doesnt discharge.

Some old B&W monitors will store a charge for a surprising
amount of time, never seen a color one that even made a
tick when discharging after it had sat for 5-10 minutes though.
Precisely.

Certainly a better sound than an implosion!

The best way to appreciate an implosion is to toss the picture tube into
a large dumpster and run away as fast as you can before it hits the
bottom. The WHOOMP is most enjoyable.

You're not totally wrong, but you're looking at things much differently. All
of us here have seen and heard where house fires were started by overloaded
outlets, especially where the person (or tenant) did not understand about
electrical current. One hundred devices would not overload a circuit UNLESS
a certain number were actually in operation. A constant 12 amp current draw
might start a fire in a given extension cord, especially because these type
items are often manufactured substandard these days.

In the UK, each device may be limited to 13 amps, but that's no assurance
that several devices operating within their limits would not overload a
given outlet strip. One cannot absolutely trust a circuit breaker. Fuses can
be mislabeled or defeated.

Also, where there's current-flow, any contact resistance generates HEAT. A
loose plug or socket can be frying inside a wall outlet or outlet strip,
even with moderate current flow. If for example, no one were home to see or
smell it, or if a person with disabilities could not correct the situation,
one could return home to a charred pile of rubble.

Once again, we're talking about an unknowledgeable tenant. A friend of mine
had major damage to a rental property because his tenants were stupid this
way.

Even in the UK, things that could cause electronic failure
as posted still apply. Need for computer and printer to share
same safety ground. Need for the AC mains to be properly
earthed. Fact remains - overloaded wall receptacles still do
not cause electronic damage. Even if the tenant had to many
appliances on a wall receptacle, that still does not explain
electronics damage. No matter what size fuses were in his UK
power plugs, electronic failure would not and should not be
created. Fuses do not stop or permit electronic damage. The
tenant complained of electronics failures. The landlord
provided no information that explains that damage.

Sadly it is you who is " pig ignorant ". Over the years various methods of
protection have been tried. Bonded face plates was just one. Other sets used
a separate flat glass in front, or a tensioning band to prestress the face.
All three are capable of implosion if removed from the cabinet and then
impacted. I suggest you return to your hole/rock/whatever.

My grandmothers house nearly burned down a few years ago from this. The
circuit was not overloaded, but the refrigerator was on the end of a run and
an outlet in the middle devloped a loose connection. The load of the fridge
and the resistance of that outlet caused it to heat up and melt. The
contacts inside the outlet were glowing red when she noticed the coffee
grinder plug fall out of the melting outlet and ran to shut off the breaker.
Replacing the receptacle and trimming back the oxidized wires fixed the
problem.

Won't kill you but it might well scare the crap out of you and cause the TV
to be dropped on your foot. I always discharge a tube before handling it,
I've been zapped a few times by being careless, wasn't hurt but it wasn't
pleasant in the least. I have sliced my hand open pretty good a couple times
jerking back from a minor shock.

While they will be useable for basic TV servicing, a good scope can be had
on eBay for not much more than an old Eico type. For some reason they have
been selling for very little money in recent months - over supply I guess.

You're very unlikely indeed to be holding it where
its likely to drop on your foot if it does bite you.

I always discharge a tube before handling it,
Sure, some are excessively cautious like that.

I personally take more risks, including building my house
in the summer just wearing shorts and what we call thongs,
most of the time, even when welding overhead on the steel
structure of the house. Sure, it was a bit of a nuisance when
one bit of slag ended up between my toes with me standing
on a ladder welding, but just a nuisance.

On another occasion I ended up with significant
sunburn on my legs because I was welding quite
a bit of stuff on the ground with me sitting with my
legs on either side of the work too. Just a nuisance.

I've been zapped a few times by being careless, wasn't hurt
but it wasn't pleasant in the least. I have sliced my hand open

Cant say I ever have, and I dont normally bother to discharge
the tube unless I actually have a faulty HT lead etc.
 
Thanks for your help and ideas. Yes I admit I was looking for the quick
fix. I'm going to need to remember my more in-depth troubleshooting
skills, limited as they are. (I worked as an electronics technician
about 20 years ago, used to do some component-level fixes of Macintosh
power supplies when I was working as a consultant, and have built small
projects). I do have a DVM and an oscilloscope, and 2 good units to
compare with. I wonder if I should invest in a capacitor checker. Kind
of makes sense that capacitors would be more likely to degrade than a
silicon chip or transistor. Would a resistor drift over time if there
were no current running through it? Yes, some of this is guesswork, but
it can be useful if in the exploration and exchange of ideas, I get
more of an idea where to focus once I get down to work.

The front is by far the strongest part. Also, modern tubes have some
implosion protection, they will implode however when struck in the right
way, just a bit less impressive compared to the older ones.

On topic: I agree with you that it's hard to have a violent explosion
on modern tubes, though. How come you are so sure that before
the advent of integrated implosion protection, this was also the case?
I might just have had quite a bit to do with those too.

If it would have, then why design new and safer tubes?
The usual reason, bigger tubes become more practical.

Cited are things totally irrelevant to the OP. Why discuss
"unfused plug adaptors" when there are none? Why even raise
this totally irrelevant issue? Apparently all power cords had
13 amp fuses or equivalent protection. Apparently his loads
were so small as to not even blow those 13 amp fuses.

I don't even know what the OP was about at this point, the discussion has
morphed onto other things.

Now that you've done it send me that 10,000 and I'll turn it into alot of
things. A new exceedingly expensive wiper delay switch for my car, some beer
for my buddy to change it out, etc.

But then again you get this oceanfront property in Belin, New Mexico U.S.
Beautifully situated in wide open spaces. Not much foliage to clear for your
house/barn/cabin, whatever.

The only minor problem is that we forgot to pay the property taxes for the
last,,,,, lemme think here,, , , , ,43 years. I haven't been there for years,
for all I know there could be a burgeoning metropolis grown up around it and it
could be worth as much as $1000 per square foot. DID YOU HEAR ? $1000 PER
SQUARE FOOT ! ! ! ! ! !

Don't miss out on this golden opportunity ! Send the money now !
