They do with with DLP lamps. OEM bulbs over here generally cost $80 U.S. give or take. People started buying ebay and Amazon lamps for a third of the cost of OEM and finding out they were either crapping out immediately or within a few months. They generally are not as bright as well. People started avoiding the cheap lamps.

A few sellers have been selling counterfeit Philips bulbs at prices just below what Philips lamps sell for - seems like a great deal on Philips brand bulbs but it's the same old crappy lamp at a lot more money.

If they have an largish item that has been taking up space for a while with no sale - they put it out the front with a sign:

" Today's Special "

With double the previous asking price.

People are funny about things.

I know a man that sells cantalopes and other items at a farmers market.

He had them for $ .25 each and not selling. He took that sign and
marked through it and made it 3 for $ 1. Sold most of them at the higher
price. People did not do the simple math and see that they were paying
about 8 cents more for each one.

Here in Canada, on our national radio station CBC, we get a fellow named
Terry O'Reilley on the air with a show called "Under the Influence" -
which is all about advertising. Where this story is leading is he had a
great show on pricing where he talked about the above subject and
people's perception of prices and what influences them.

The episode is: S3E02 (Archive) - The Psychology of Price

Listen to it here:

http://cbc.mc.tritondigital.com/CBC_UNDERTHEINFLUENCE_P/media/undertheinfluence_20140110_46407.mp3

Or go to the main page at and track down S3E02:

https://www.cbc.ca/radio/podcasts/arts-culture/under-the-influence/

I've been listening to him for years, lots of great info on how
advertising (both good and bad) influences us.

'lytic caps go bad eventually. After removing the caps for testing you've already run the risk of damaging the board.


Anyone who would ruin a board by removing a cap isn't a professional and shouldn't be playing with it. There is ZERO chance of damaging even a multi-layer board.

I'm interested to hear how you remove caps from paper based boards with zero board damage rate. Early paper PCBs are somewhat notorious for tracks coming off when heated.

Right, at the small cost of the capacitors, it is foolish to put backin
an old one even if the board may have other problems and not used.


I've read that sentence like 5 times and all I can say is that you wouldn't be working for me..

Honestly, sometimes I wonder if people just post because they want to say *something*.



I doubt that I would work for a tightwad like you. If those capacitors
are less than one dollar, it will take more time to test and replace
them than the labor would pay.

Lets say I just make $ 20 per hour. It may take me 5 minuits to setup
the capacitor checker and test it.

Takes me about 10 seconds. I like to know whether I've found a fault or need to keep looking.

A very hot iron wetted with fresh eutectic solder, together with expeditious use of a solder-sucker will pull the solder and loosen the lead without damage. It is the sustained heat that causes the traces to lift.

Horses for courses.

Takes me about 10 seconds with the ESR meter, containing a 12 volt battery. Takes a bit longer on the big checker that operates at up to 550 VDC.

Which do yo think will give the more reliable results?

It's that simple.
I've been doing this for 50 years now.
I don't lift traces, or break off terminals unsoldering
things.

550v will tell you more about leakage, not more about ESR.

Sure you did. You asked *me* "...how you (meaning me) remove caps from paper based boards with zero board damage rate."

This indicates you can't.

The idiot's a troll. Look back at his previous interactions with others
here and elsewhere and there's an unmistakable picture that emerges. I've
KF'd him. You can waste *so* much time on pricks like that if you're not
careful.
