[Hallicrafters] S-120 Front Panel Corrosion?

[Philip Atchley]

Joe et al,

Besides the brand new one I bought in 1963, I've had maybe three S-120 
receivers in recent years.  All of them (except the new one in '63) had 
flaws similar to what you describe. While I never removed the panels, I 
suspect it may have been something in what they coated them with, that 
or oxidation.  I've seen something similar on Eico Test Equipment having 
brushed aluminum faces.
