[Hallicrafters] S38 Front end

[Kirk Z Bailey]

VERY good one, all things considered. Still, I am amazed that they did 
not save a little more by using a 70L7GT and using only 4 tubes- which 
would have been a very noteworthy saving on overall costs.

If I find a rough but workable S38A, I will do the minimum to get it 
working and safe, then remove the 30Z5 and 50L6 and replace them with a 
70L7, and see how it sings for me. IF and WHEN I do this, I will notify 
the list.

Yes, double shielding and proper attention to precision of mechanical 
linkages and structure contribute to the quality. One of my likes about 
the S38 and the A is they are mechanically stable and certain in their 
action, where as my Mark 2 E is sloppy with play apparently from 
structural members flexing under the tension of action.
