Can metal chassis become defective? I

I have learned from a top repair technician with 45 years experiance that all internal electronic components can go bad after enough time (resister, caps,tubes) INCLUDING the actual metal chassis. He claimed that if an old unit is not working that you could replace ALL the electronic components and it still may never work because the metal chassis is WORN OUT. His theory is that the electrons that go into the chassis ground have (over the years) filled up the outer atomic orbitals and interatomic space with too many (used) electrons forced into the metal (aluminum for example) and that the metal is now defective for a ground chassis SINCE THERE IS NO SPACE LEFT FOR THE ELECTRONS. The metal is WORN OUT. It becomes a radioactive isotope of aluminum since there are excessive electrons in the outer orbitals, and unusable as an electronic chassis. If this is not the case then where do the electrons go if the chassis is not grounded to true earth ground (cold water pipe only)or through a proper three prong plug?

Trelja's right. I own an 1886 Victorian, and one night in the middle of the Mahler 2nd, as the chorus was singing towards the heavens, the electricity in my house just went off! I went outside and the rest of the neighborhood was fine. Turned out my electrical wiring in the house was completely saturated after around 100 years of use (taking into account the gas lines that were used in the old days), so I had to re-wire the whole house. Of course, I took this as an opportunity to wire with Purist Dominus throughout the house, which has improved my sound dramatically.

Joe, I hope you have more success with your utilities in PA than I did with PSE&G in trying to upgrade the neighborhood wiring.

Joe, thanks for the kind thoughts. I wanted very nuch to go and meet some of the Philadelphia members; we'll probably have one early next year at Community Audio, maybe we can work another joint meeting then. Hope to see you at least at the holiday party, already picked up some nice door prizes!
