They are used differently.
For example, the audio driver stage in 116 uses 1 tube, and in 37-670 it uses three tubes: a phase inverter, then pushpull transformer driver.
Which means 116 has an advantage of pure amplification somwhere by using 2 tubes for it remaining from being utilized in the output driver.
But then it has to be seen if there is some slight advantage that 37-670 achieves in the audio amp section.
