Audio Tweak gone bad...similar experiences?

Many of those 1982's were machine stamped at the Denver mint at a time when that facility was undergoing quality control problems. It seems the Mint had outsourced to a foreign copper source which had questionable links to anti-American groups abroad. Much of that copper has been determined to contain nanotechnology (even before it was developed) that disabled electronic devices of any kind and has been unknowingly introduced into any products manufactured from that metal. Anyone in posession of such coinage or other copper products is in very serious personal danger as are their electronic posessions. You probably got one of the 'sleeper' coins programmed to cause American electronic devices to self-destruct at a preordained time. You may well have discovered the initial phase of a foreign attack marking the beginning of the first wave of a sleepers awakening to begin their attack on unsuspecting Americans and our very way of life.

Fortunately, have developed a disarming device for such subversively contaminated copper which is very similar to the flux capacitor and which operates on similar principals by channeling the nanotechnological particles into a time warp and sending them to a time before copper was invented thus rendering them ineffective. I can sell you this device for a very modest $199.95 (PayPal transfers accepted). Surprisingly, it looks very much like a Timex battery clock. But don't be fooled. It has subtle proprietary modifications I am not at liberty to disclose.

you should have cryoed the penny

Your problem was that you were one penny short. Just my 2 cents..........

All this makes no cents!

An atomic clock on top of each speaker works wonders. Might even fix your problem.
