My inexperience catching up with me

[Enzo]

Perhaps I need to go back to school.

Elsewhere around this place I was told that my feelings on a certain line of substitute semiconductors was a result of my laziness and lack of troubleshooting ability.

Then in another forum where we were discussing the sound system for a conference/meeting room in a hotel, specifically driving an array of 8" ceiling speakers, I mentioned that I thought one suggestion for multiple amps and delay lines was overkill, I was told that I should keep my thoughts to myself because I obviously had no experience whatsoever.

Not bad for one day.

So I guess it is back to school for me, then hopefully I can find a job in the industry to get some badly needed experience.

How DARE you trot out a mere 30-40-50 years of experience successfully repairing things and hope to "hold a candle" to a well-schooled person (who may still mentally say "lefty-loosey righty-tighty" while manipulating a fastener). The audacity - it's, well, mind-boggling!!

Words fail me - please envision a middle finger pointed in the appropriate direction...

Enzo, I am not sure if that line of substitute components is the company that I am thinking of, but a tech that I worked with a while ago assured me that they were better quality components than any other. I asked him why he thought that and he said "because they cost more". It's hard to argue with that logic...

[Enzo]

Well, you know, West Michigan.....

So the can of Niblets corn at the 7-11 store is better than the same can of corn at Kroger? 'Cause it costs more?

I continue to learn...

[tonedeef]

Yeaahhh, that same tech had an amp on the bench with a "signal present" led that stayed on all the time, the unit functioned perfectly, so his first thought was that it was a bad led. And yes, he did swap it, it still stayed on.
What really gets me is that he is a well respected tech.

[Enzo]

LEDs that won't go off MUST be bad...

[Techknowman]

Also don't forget, you must insulate the end of all loose wires or the electrons will leak out all over the place.

f that guy when you were sick it was like Santa phoned out on christmas!!!

oh and for fun...

Wow. So he had a whole drawer full of defective LEDs? That's some bad luck.

Some days I really wish that was the case. I wish I could just buy every NTE part. Then I could fix ANYTHING!

[Jazz P Bass]

NTE parts are not bad nor are they inferior.
It's just that they are not very particular.
(Can you say NTE123AP?)

[J M Fahey]

I'd love to have a LED which produces light with no voltage applied to it
(Otherwise it would not be "bad", isn't it?)
Nobel Prizes are given for lesser discoveries than that.

As to ENZO: forget Electronics 101, that's too advanced, I suggest the Kindergarten where I sent my children, the beautiful teachers there taught them to do all kind of nice things with Play Doh and similar advanced technologies.
In fact, *I* wanted to go there and learn something.
No, the fact that the teachers were yummy had nothing to do with it.
Drool.

Just expensive and non-specific.

Enzo, it's not just the electronics profession. I had a young fellow come by a few weeks ago, wanting me to plug in my scanner, and tell him why his car was missing. I could hear from the exhaust that it was internal. I unplugged the coil packs, and cranked the engine, had a definite skip in compression. Gave him a price for pulling, and inspecting the head, he told me I was just trying to take his money as there was no way I could tell he had a compression problem, without scanning the system.
I agreed that he better go let someone else perform all the tests. He actually called back after going to the dealer 50 mi away. They charged him $150 to tell him what I did, so now he wants me to pull the head. Told him I was too busy.

In a room big enough to need more than four cieling speakers OR if the volume is adjustable in separated rooms I could see the need for delay lines. But if it's the typical piped in Muzak at a fixed volume in each space delay lines seem like overkill to me too. Too many people just want to implement intricacies because they're cool or because they don't know they don't need them. They say to hell with a clients money. I say Muntz the delay lines.

To the young or overzeleous the practicality of experience can seem like ignorance to modern trends. Of course modern trends follow advances in technology, which is also important. But the world is full of trend seekers that love to attach the latest glitter whether it's appropriate or not. Believing that anyone who doesn't is crude and uninformed when exactly the opposite is true.
