[AMRadio] Question: What rigs used the 4-400A ?

[Charles Ring]

The .pdf manuals I have for all of the Globe King 500 series call for a 
4-250AX except the 500C calls for a 6156. My 500A had a 6156 when I got 
it in 1972 and when that tube shorted F-G I replaced it with a 4-400A. I 
see no difference in the specs of the 4-250A vs. 4-400A except plate 
dissipation.
