Hi
No, the 42 audio output does not require a tube shield.
In the model 60, only the 6A7 det-osc tube, the 78 IF tube and the 75 2nd det tube used tube shields. And in later 1936 versions of the 60, the 6A7 did not use a shield.
The shields are very important, however, on the 78 and 75 tubes, The radio will squeal badly without them.
