[Amps] Henry 4K Ultra - Military SErvice Manual ?

[Dave, K2DP]

OM's,

If anyone has the military service manual that Bob is referring to, I would 
also like to get a copy of same. OUr radio club has inherited this amp and 
it's well worn linkage is going to need some alignment in the not too 
distant future !

Many thanks,
Dave, K2DP, St. Louis
