[BC] Achieving good S/N

[Milton R. Holladay Jr.]

All of the 3 Fairchild models that I have, have only one motor.
SC ETV Radio had 4 of the EMTs when I was the supervisor there in the early
80s. There were no problems with rumble or flutter. They had a rumble null
pot that was in series with the motor condenser, to adjust the phase a tad,
leading me to cognite that the size of the motor capacitor was somewhat
critical to smoothest operation. Could the ones you had have been a bit off
value?.....
