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. ** Reminds me of the old trick used by many dealers in second hand furniture. 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. .... Phil |

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 he http://cbc.mc.tritondigital.com/CBC_...0110_46407.mp3 Or go to the main page at and track down S3E02: https://www.cbc.ca/radio/podcasts/ar...the-influence/ I've been listening to him for years, lots of great info on how advertising (both good and bad) influences us.

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. NT |

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. Peter Wieck Melroes Park, PA |

Takes me about 10 seconds. I like to know whether I've found a fault or need to keep looking. 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? Peter Wieck Melrose Park, PA |
