[TenTec] T-T Knob Inserts

[<richard.arland@verizon.net>]

One of the things I absolutely HATE when trying to restore a T-T radio is the 
knob inserts that are discolored. One of my students, who also colletcts coins, 
said that the solution would be to put the knobs in a solution of salt water. 
The salt apparently reduces the oxidization returning the insert to almost new 
condx. I have tried this on some Argo 509 knobs and it seems to work. Once 
treated I spray the knobs with some clear Krylon to seal the aluminum surface 
and prevent any further corrosion.
