(to give credibility to this article I need to say that I am an Audio Development engineer with over 30 years of electronics engineering background in the actual electronics industry - just so you know...) Take a look at a metal film resistor spec. What do you notice? Temperature range: -55 to +155 degrees Celsius As I told people two years ago, Tin, not alloyed with corrosion protector Lead, powders up (given time) long before reaching -55 degrees Celsius. The resistor manufacturer also knows that fact, and therefore has replaced the tinned coating on the wires with Silver. When you solder the resistor in circuit (use any solder you like) you form a junction of dissimilar metals - a thermocouple! Therefore, a new RoHS compliant circuit has tens to hundreds of new thermocouples. And it's not only resistors that have coatings other than Tin on their wires. The net effect is not only to alter the sound balance in an audio circuit (although the test gear still tells the same story), but also to make the sound balance change with temperature more than ever before. Clever Eh? ;D Thick more like! (since when have politicians been electronics engineers???) "These are dangerous times we are living in" Mike and the Mechanics

Obviously, politicians not only don't know their electronics, but they also don't know their history.
When Napoleon invaded Russia, the freezing temperatures of the Russian winter caused all the tin buttons on the soldiers uniforms to dissintigrate which contributed to half his army to freezing to to death.

"Tropical Audio Products Inc""Hi,my name is Chico and I want to introduce you to a brand new line of audio products that cut out 50% of the global market but then we don't like those cold weather punks anyway. What do they know huddled in their dark gloomy homes living miserable lives.Four seasons ? Winters ? Cold and dreary ? Why would humans even live like that ? So join me in "fun in the sun music to go any time,anywhere" and let everyone else wish they were us as we party on into the night !
Thank you for looking,
Chico" Just wait folks,it gets better and better.Next up on the hit parade is "energy efficient" and that means use a linear power supply go to jail. So we can all at that time use our energy efficient cell phones to download songs at a buck per song,play them anywhere while talking to freinds and family but oh by the way,they also will be copy protected so don't even think about sharing ! Lossy compresssion,overpriced one hit wonders,temperature variable parts (think of it as a free tone control ),Wi-fi.....DAMN ! No reason to ever go home unless I need a drink or want to have a smoke which are also on the "hit list" of the PC Police ! "The future's so bright I gotta wear shades" (Timbuk 3)

BTW-if anyone is interested in the "next wave" I can provide the links to the early stirrings on the energy efficient front which while seemingly of no importance are just the opening shot and are at the point where the RoHs fiasco once was.
At that time no one noticed the movement and those that did either had no worries or flat out did not care yet here we are with a two by four right between our cheeks and no way to pull it out without some serious bloodshed (Splinters,OUCHY !).
As high density LSI becomes the rule and the cell phone moves closer to a "whole world everything interface" all things audio/video will be relegated to wireless networking with a central server as "system" that can be accessed from any place any time by any body with the passwords.
This may suit the pimply faced crew who truly beleive a lossy MP3 is a true high fidelity format or the computer geek who likes everything in a tidy "one" or "zero" package but is hardly what I personally consider a good thing having a background based mostly in analog and one who has seen crap become "good" and and at times GREAT even though the head to head says someone is pissing on my leg and trying to tell me it is raining
