[Hallicrafters] HT-32B (David C. Hallam)

[David C. Hallam]

That's what is in mine.  But what I am trying to find out is, did 
Hallicrafters make the shield out of Mu metal to provide a magnetic 
field shield for the 7360 or is it just to conduct heat to the tube 
shield?  The 7360 being a beam tube is very sensitive to magnetic 
fields.  Mu metal is a nickel alloy that is used for magnetic field 
shielding.
