Standed wire wears out sooner than solid wire. Thin chassis wear out sooner than thicker(gauge) metal. Aluminum wears out sooner than cooper, brass or stainles steel. Therefore inorder to restore an older tube amplifier,you will need in addition to all new caps and resistors ; all new solid wire and thicker gauge stainless steel chassis. Only transformers improve with age. Have you ever noticed on very old tube equipment that the old aluminum chassis appears to have a whitish "patina"? This is PROOF that the chassis is defective for use as a conductive ground, this is not rust or oxidation since aluminum cannot rust. These chassis are toxic and have transmuted into a radioactive isotope of aluminum and can cause anemia and bone cancer.
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?
